Sounds like the trans is causing it to stall out, every time you restart the car, you reset the computer,not clear any trouble codes that might be stored, but you reset it's drive cycle so to speak.Here is a brief description of your computer system.

The Chrysler fuel injection systems combine electronic spark advance and fuel control. At the center of these systems is a digital, pre-programmed computer, known as a Single Module Engine Controller (SMEC) for 1987-89, a Single Board Engine Controller (SBEC) for 1990-91, a Single Board Engine Controller II (SBEC II) for 1992 and a Powertrain Control Module (PCM) for 1993-95. The SMEC, SBEC, SBEC II or PCM regulates ignition timing, air-fuel ratio, emission control devices, cooling fan, charging system idle speed and speed control. It has the ability to update and revise its commands to meet changing operating conditions.

Various sensors provide the input necessary for controller to correctly regulate fuel flow at the injectors. These include the Manifold Absolute Pressure (MAP), Throttle Position Sensor (TPS), oxygen sensor, coolant temperature sensor, charge temperature sensor, and vehicle speed sensors.

In addition to the sensors, various switches are used to provide important information to the controller. These include the neutral safety switch, air conditioning clutch switch, brake switch and speed control switch. These signals cause the SMEC, SBEC, SBEC II or PCM to change either the fuel flow at the injectors or the ignition timing or both.

The SMEC, SBEC, SBEC II or PCM , are designed to test their own input and output circuits, If a fault is found in a major system, this information is stored in the SMEC, SBEC, SBEC II or PCM for eventual display to the technician. Information on this fault can be displayed to the technician by means of the instrument panel CHECK ENGINE light or by connecting a diagnostic read-out tester and reading a numbered display code, which directly relates to a general fault. Some inputs and outputs are checked continuously and others are checked under certain conditions. If the problem is repaired or no longer exists, the The SMEC, SBEC, SBEC II or PCM cancels the fault code after 50-100 key ON/OFF cycles.

When a fault code is detected, it appears as either a flash of the CHECK ENGINE light on the instrument panel or by watching the Diagnostic Readout Box II (DRB II). This indicates that an abnormal signal in the system has been recognized by the SMEC, SBEC, SBEC II or PCM . Fault codes do indicate the presence of a failure but they don't identify the failed component directly.

FAULT CODES

Fault codes are 2 digit numbers that tell the technician which circuit is bad. Fault codes do indicate the presence of a failure but they don't identify the failed component directly. Therefore a fault code and a result are not always the reason for the problem.

CHECK ENGINE LIGHT

The CHECK ENGINE light has 2 modes of operation: diagnostic mode and switch test mode.

If a DRB II diagnostic tester is not available, the PCM/SMEC/SBEC can show the technician fault codes by flashing the CHECK ENGINE light on the instrument panel in the diagnostic mode. In the switch test mode, after all codes are displayed, switch function can be confirmed. The light will turn on and off when a switch is turned ON and OFF.

Even though the light can be used as a diagnostic tool, it cannot do the following:

1. Once the light starts to display fault codes, it cannot be stopped. If the technician loses count, he must start the test procedure again.

2. The light cannot display all of the codes or any blank displays.

3. The light cannot tell the technician if the oxygen feed-back system is lean or rich and if the idle motor and detonation systems are operational.

4. The light cannot perform the actuation test mode, sensor test mode or engine running test mode.

Be advised that the CHECK ENGINE light can only perform a limited amount of functions and is not to be used as a substitute for a diagnostic tester. All diagnostic procedures described herein are intended for use with a Diagnostic Readout Box II (DRB II) or equivalent tool.

The SMEC unit, is located in the engine bay on the d.side fender towards the front of the vehicle.This is for the engine.There is a blue BUS diagnostic connector for the trans inside the vehicle that also requires the use of a scan tool.It uses a seperate control module for the trans and uses an adaptive shift strategy,like stated above, basically learns how you drive and will reset itself when you cycle the key off and on if it sees a problem. Reverse is basically a hydraulic gear that most vehicles will always have reverse gear and at least one forward gear range when there is a problem with it. If you have no reverse,it is an indication of an internal hydraulic/mechanical failure.

You need to have it checked by a trans shop. Not much you can do without a scan tool other than what I mentioned in my previous answer. The trans control module says it is on the right side of the engine bay but my illustration shows it in the center of the engine bay on the firewall.
