02 7.3 randomly shuts down
First time posting, but I have gotten a pile of good info from here. I'll get right to it. I have a 2002 f250 7.3 with 136,000 miles and only a few mods. For the past 2 weeks, my truck has randomly shut down on me. No sputtering, just like you turn off the key. There is no pattern to it, other than it has gotten progressively worse. It has idled in the driveway for hours with no problem and it has fired up, ran for 5 minutes and shut down. I have shut it down myself and immediately start back over and over with no problem and have tried the same and it not start. Motor hot or cold has no effect.
Things I've tried-
-3 different cps, 2 cheap, 1 grey motorcraft. (Had cps recall done in 09)
-No oil in icp, unplugged icp when motor wouldn't start, crank but no start.
-pulled and cleaned ipr valve
-checked hpop oil level multiple times, always good.
-changed hpop oil, when ipr was cleaned.
-unhooked dp tuner, nothing modified electrically.
-shook every wire under the hood with truck running.
-hooked up 2 snap on computers with no codes showing
-ran injector tests with computers, set no codes, passed the test.
Any input from anyone would be appreciated.
I have been stuck on the side of the road twice now, with 2 small children. It's not an enjoyable experience for any of us.
