Increase RPM's on fuel pump and the car shuts down when the fuel pump increases in RPM's. Its like trash in the line blocking the fuel from the pump. i have already changed the fuel filter and the car continues to have the same problem. Both times it happened i had a quarter of a tank or less which may be coincidence.

If the car in park you shouldn’t raise the RPM
ECM will limits the injectors to protect the engine from mechanical failure
if while driving
I would check for tune up
check fuel pressure and scan system for codes
good luck
