Message: [QUOTE="Ford7.3SD, post: 1275530, member: 10"] Its been a while since I have posted on the forms, but I'm having an issue with my 2001 that is stumping me. The truck will start/run/drive just fine in the morning. It will run for around a half an hour or so until its nice and warm and then it will just cut out, no stubbles or any warning that the truck is acting up. Then it won't start for around a half hour, after a half hour or so it will fire up and run just fine until it cuts our again. I found the IPR wires to be disintegrating, so I replaced it with the Ford repair harness. no change. When it restarts, it acts like its slowly building oil pressure until it fires up. 1) while dead the truck will crank and crank with no build in oil pressure. (I have a gauge plumbed in to the passenger side oil rail) 2) oil pressure at full throttle struggles to go past 2K in my 140 race tune and maxes at 2500 but it only spikes to that PSI. 3) CPS is brand new 4) no codes are thrown when the truck dies Any help to get me pointed in the right direction would be awesome! Thank you!! [/QUOTE]
