It seems like its losing fuel pressure. Had it at the boat ramp last night. it can run at 3000, 3600 rpms no problem. but as soon as i try to get 4500 rpms it stumbles once or twice and dies. checked last night still have voltage to ECM. still have voltage and a good ground to VST. After it dies i turn the key off then on to see if i hear the the pump come on and nothing, i have to smack the vst to get the hi- pressure pump to come back on. I would think bad pump but its only at a high rpm that it does this. I know the ECM is good. not sure what direction to go. If the injectors were dirty would it cause this. any ideas or suggestions would help.
