Truck shuts off on its own intermitently?

[Danimalm37]

Hi everyone. Just posing up a question about a truck I'm looking at buying. Its a 95 Ford F-350 powerstroke." This is the cut and pasted comment from the craigslist ad. "it turns on and then turns off; sometimes it lasts a couple of days other times it turns off after 10 to 15 minutes; the fuel filter light goes on and goes off" I'm not sure what exactly this could be I have general mechanical knowledge but I don't want to buy a money pit. The truck is $1500. If any of you have experienced this or know whats causing it could you let me know. Thanks in advance, and if I purchase the truck I'm sure I will be seeing more of you guys. Have a great new year.

The intermittent shut could be the CPS (Cam position sensor) going bad, approx $20 - $30 fix. If it won't start while turning over, watch the tach. If the tach doesn't move it is probably the CPS.

I believe bad IPR o-rings will cause no start issues as well. If the truck is shut down after running for a while and won't restart, this could be the culprit. O-rings on line mid 30's IIRC, at the dealer $50 - ??.

Someone with more knowledge should be along and can confirm what I have posted or correct me.

Hope this helps.
