Only light that comes on is the fuel filter restriction. Drove truck for a solid three days without a issue then under a hard pull it started same issue. Replaced injector cups as well as the overflow valve in front of the head. Ran great for a few hours now same ordeal all over again.

Mp8 starts ok and idles ok most of time. Sometimes you give it throttle and its perfect then the next second it seems like its starving for fuel. Runs very rough then will eventually die. Has new fuel pump and filters. Truck is deleted except EGR. Shows low fuel pressure via laptop. At times it reads 0PSI but is still running. Any help would be appreciated.
