Guss101 I did, couldn’t find any signs of it leaking, didn’t look cracked or any wet spots anywhere, but I’ll replace it just cuz it’s old and simple to do. Plan on pulling the pump this week. Hope I can report back that I made the right call lol
Thanks everyone for your suggestions and help.

Did you check the hose between the prefilter and pump?

Not running on all cylinders is a lot different than randomly dieing. It would be great if you were consistent and accurate in the description. Pressure dropping to zero when you shut it off is normal.
GAmes I really appreciate your help, I know you are very knowledgeable, I on the other hand am not. I’m self taught 90% of that is from reading on here. Reading and writing are not my strong suit, hence my low post count. None the less I’m trying to give full and accurate information to the best of my knowledge. Yesterday it dawned on me that it sounded more like loosing a cylinder, again learning as I go. Sorry for the confusion

Truefat I think if plungers are sticking there would be scuff marks on the barrels. Is it possible to visually examine the barrels with the delivery valves out?
You should also try to confirm that the pump is a 180 and not a 160. It could have been swapped.

Guss101 I have good fuel pressure though, 25-30psi. Although pressure bleeds off as soon as I shut off the truck.

My truck did this when the ofv was bad. It could be anything really.

With good cause. It is a very good way to render your p-pump totally inop. The tq for the barrel bolts isn't published because Bosch keeps a tight rein on it's product. Only the early pumps were known for their warped barrels and sticky plungers. The symptoms are only apparent when the pump gets heated after operating awhile, not on start-up. I've never heard of one where the engine died out of nowhere, then cranked and ran like nothing was wrong. The quick and easy check is to pour some cold water over it when the engine misbehaves. If the symptoms go away it is pump rebuild time. I doubt that is your issue.

Its actually never done it when the motor is cold. But when it straitens out it’s still warm, never had to let it sit more than couple minutes maybe.

nSaEvAyL I have racked 7 trucks over the last 10 years and all of them have been fine. I have known at least 25 people who I have met a various events who have racked. All of them have been fine.

Everyone of my personal trucks I have racked.

Last I torqued my housings I used 30 ftlbs.
