Hi Customer (name blocked for privacy),
Check your alternator and battery. I suspect the alternator is intermittently discharging or has a failed internal diode. It may have already caused damage to the battery. Your fuel pressure is right where it needs to be and the regulator putting out the correct amount of pressure when you rev it up. Here is the issue, The Computer uses a 5v reference signal to fire the fuel injectors and if it gets below or looses the 5v reference signal the fuel injectors will not fire. How is this possible?? If the alternator is failing to do its job or the battery is intermittently internally shorted it can cause this issue. Meaning the vehicle is running off the battery volts only and or drops voltage to the computer which shuts off the fuel injectors. This would also effect the starting characteristics of the vehicle. Other than that, looking to make sure you have a 5v reference at the fuel injectors at all times from the computer and it receives a negative trigger signal from the computer..there may be loose or bad connections. Also make sure there is no corrosion at on on the battery terminals. The first step i would Take would be to install a new or well know battery for testing.
