high pressure oil leak developed and when that occurs the truck will stumble fall flat on its face and die, unless you hold it wide open. Happened to me a few times. Had replaced a bad injector was driving it and watched the icp pid drop from 2-2800 down to 1200 and once it hit 800 i held it wide open all the way back to the shop until it died in the driveway.
Turned out the stand pipes and dummy plugs were fubar.
Also had a customer install an "upgrade" put a resistor inl ine of his icp sensor which caused the ipr to eventually fail which caused the same thing. Not that the screen blew out, the solenoid inside the IPR burned out from being commanded much higher than need be at all times. Only when people install a resistor to the icp sensor, it causes the pcm to think the ipr isnt doing its job so it commands it higher causing more Pressure to go to the injectors which is believed to give more power but really causes more problems... Ive seen it alot in 7.3s only once in a 6.0
