Hello and thanks for your question. My name is XXXXX XXXXX I will do all I can to help.
The first thing I would do, is put a fuel pressure gauge on the engine. If it's a fuel pump, or faulty fuel pump relay, That will cause a lack of fuel pressure and make it shut off.
Usually when the crank back up, it is fuel pressure related. even a slightly clogged fuel filter can cause this, but usually it's the fuel pump circuit or the pump itself.
Put a fuel pressure gauge on the engine when it is running, note the pressure, then watch the gauge , See whether the fuel pressure drops when the engine shuts off or not.
Also, have you scanned for any trouble codes yet? Let me know.
We have not scanned for any trouble codes and nothing lights up on the dash board indicating a problem. The check engine light does not come on nor did it come on when the starter and alternator failed and battery. I also notice when the car dies out, it happens many times when I am pushing my brakes. Another thing I notice is that when the car dies out I go to start it and it won't start but the car still has something running because I turn off the key and the all the lights on the dash light up, I can hear the fuel pump running and the car makes a flickering noise, like when the car is trying to crank over but you need to fool around with the cables for the battery. I touch the negative cable for the battery and it seems to fix it for the moment. Sometimes when the car is off and the ignition is off, I push my brakes and the lights come on the dash board. Do you think there is an open circuit or a ground?
Is anyone there to answer my questions?
