Hello and welcome to JustAnswer!

If the engine dies and the fuel gauge and voltmeter go down at that time, and there are no other electrical issues or warning lights, then the powertrain control odule is going down. The PCM is the module that controls all engine functions.

It will take some electrical testing at the time the problem is happening to determine exactly what is going on. The problem may be an internal failure in the PCM, a loss of power or ground to it, a short to ground on a reference voltage circuit or short to voltage on a sensor ground circuit. These could be wiring issues or internally shorted sensors.

If everything checks out at the time the problem is happening then the PCM will need to be replaced.
