No start after 30 secs. of running
 

I have a 2005 6.0 that runs for 30 secs then it lugs down and will not start until you let it sit for 5 mins.Connected scanner no codes while monitoring injection pressure with scanner psi actual is 840 while running matches desired psi. when it starts to lug down at idle desiredis 1000 and the actual starts to ramp up all the way to 2500 psi then it shutts down. will restart in 5 mins. but the same thing happens again? IPR has been changed. Im thinking there is some kind of resriction in the high pressure oil system causing pressure to go up? Anybody have any ideas ?? thanks for the help:-huh:-hair
