My engine will run great till I hit about 52 mph and then it will bogged down and the rpm's will drop to around 4000 and will stay. Hot foot pressed to the floor but nothing more.
It seemed to be fouling plugs very quickly less than 8-10 hrs of use
I have replaced filter on side of engine with the red float ring inside, replaced all 3 low pressure fuel pumps, changed out VST filter, cleaned small filter behind pressure regulator, had injectors professionally cleaned and flowed, cleans O2 sensor. No alarms going off.
Thought I was making progress but still doing the same thing. Can it be the high pressure fuel pump not working, pressure regulator bad, or is it a safety feature shutting down for other reasons.
