Engine Cutting Out At Random

Been searching and can't seem to find. Just put in International CPS with purple o-ring, known good IPR, good IPR pigtail, good fuel pressure, even under load, fresh oil, HPOP full, and UCVH all seem good and tight. Trans fluid full and new of course.

It has cut out on me three times today while idling. It starts right back up and has been running great, no missing or stumbling. I'll try to look further, but not sure where to go from here. I thought about ignition switch? I am sure it's something simple. You think I'd be able to solve this on my own by now...LOL

Tin nut on the IPR maybe? When I had one missing on my 96 C&C, it would randomly die, and usually fire right back up.

It was tight a week ago, but that doesn't mean it hasn't changed. I'll check again. Thanks Tom!

Ok guys, checked all of the above, CPS pigtail, ICP pigtail and connections to my Efuel and oil pressure switch. It cut out on me twice again. At a loss. No codes either. Kinda making wonder if this is going to be a wild goose chase, to which I am certainly not looking forward to.

I'd start with popping the cover on the column and start tapping on the ignition components while it running.

Wasnt it Glenn that had problems with his oil pressure switch making his cut out? Maybe try to hard wire it.

I had problems last year with it stumbling under load, but it never cut out. I replaced the switch and all has been good since then. I am not sure if Glenn has had issues or not. I am sure he will chime in. God I hate electrical sh**!!! It's just a big giant "who knows? Could be anything!!"

If the fuel heater connection is loose it might of shorted out when it hit the fuel bowl, or engine? It will not blow the fuse but it can cut power to the pcm briefly.

He has efuel so no bowl... And if he had blown a fuse it wouldn't have started back I don't think...

My money is on the oil pressure sensor for efuel.

Just for future reference. I've seen two truck have a fuel bowl heater wire short just enough to kill a truck but not blow the fuse
