You may be losing fuel pressure or have a hard fault in the electronics of the engine control system. Do this, have the fuel pressure checked and have a fault code test run on the computer system. If all is ok then the ignition starter switch is suspect as well and the MAF sensor which will not set a fault when it fails.
Sounds like you may have a vacuum leak. Can find that normally by spraying carb spray around the intake manifold and listening for the engine to idle up. That's if you can keep it running.
Have the idle bypass valve checked, also called idle air control valve.
If that valve is stuck in the closed position, it's not allowing the fuel to bypass the throttle plate to keep it idling, resulting in stalling, but will keep engine running if the pedal is pushed down.
I put a new fuel pump, fuel filter, and a fuel pump relay and the fuel pump is still not coming on. I am not getting any fuel. Can you please tell me what it might be.
