Yeah, my truck keeps quitting on me. Got gas, can hear pump running after engine quits for a few seconds, which means the pressure switch is kicking it off. Pump is working, but it seems to run out of fuel. Filter is clear, can blow through it easily. However, when I took the filter off, it seemed to be about half full. Should have drained more fuel, I think. Is there something I am not considering? I thought maybe the carb injectors, but it would be rare for both to do the same thing at the same time. It runs fine til it doesn't (doesn't miss.)

Failing fuel pump? Need to check pressure. It can run but not produce the needed pressure
