2nd time: 1996 Ford F-150, 5.0 liter, auto trans, 4x2, while traveling down the road will kick once or twice and stall. Sometimes while still rolling, will start up again. Sometimes it won't start again for between 5 minutes and 2 hours or so. The Elect. Ingnition control module, crankshaft position sensor, coil, plugs and wires, cap and rotor, fuel filter have been replaced. Relays to the fuel pumps and the injectors were swapped with other comparable relays (which were unused in the fuse box under the hood), but the problem still exists. Immediately after the stall, fuel pressure to the fuel rail was checked and it seemed good.

Any ideas?

Hi

Check the actual connections to the fuel pump for condition and integrity before you do anything else. If the connections are bad then they will heat up, cut the engine out due to pump failure, and then they will not return to normal operation till they have cooled down.
