I'm trying to diagnose a 7.3l that is having issues after medium to hard acceleration. After you hit the pedal and let off. Once almost stopped and back down at idle, the engine will bog, sputter a little and shut down. I have checked fuel pressure and i have a good solid 55 psi when this happen. Also, the check engine light does not come on. Can anyone point me in the right direction to further diagnose the issue?
