randomly shutting off?

Hi I'm new to diesel's and just bought a 97 F250 4X4.
I bought the truck sat and started driving it monday, but today after about an hour long drive at about 75 I got off and shortly down the road came to a red light and the truck stalled on me while sittin at the light. started back up after a couple crank's, then it did the same thing a little later while backing into a parking space about 3 mile's down the road. after I came back out an hour later or so it fired up and drove around the city fine with no problem's. but on the way home after the hour drive at 75 a short time when I got off the interstate it died on me again.
now I know either the fuel pump is going or an O ring is leaking on the back of the driver side valve cover, it's not a bad leak but you can tell it's their. which I'm going to be fixing this weekend.
I'm hopeing that mabye it's just getting air mixxed with the fuel and is causing it to stall out and will be fixxed when the fuel leak is fixxed. but I figured I'd post up to see if anyone knew of somthing else it may be.

unrelated I also found out that the auto locking hub's arn't locking when put in 4 wheel, is their a trick to it or is their anything that is known to fail on them that can be an easy fix. or should I just get the warn manual kit?

Thank's

Fuel filters might be plugged or the inertia sensor might be on its way out. Inertia sensor is for if the truck is in an accident it shuts off the fuel system.

Sounds alot like a CPS. Cam Positioning Sensor. They are common to go out. The good news is, they just got real cheap. About $25 or so. And the auto hubs are controled by vaccum lines. At least on the newer ones. Not sure about the OBS trucks, but it is something to look for. If that is the case, you may need some new lines that are not cracked. have you tried pulling any codes?

Oh, and to the ORG.

When your engine dies do you show any rpms on you tach? If not then your cps is going out.. Spend the money and buy one from ford... Stock hubs are a joke...Get a set of warn...I would make sure your transfer case is working first...Might not be kicking in...

Thank's, I appreciate the quick response's. I'll look into the CPS and hopefully once the fuel leak, that and the hub's are fixxed I won't have any problem's for a while.

another vote for the CPS but not 100% sure without watching it die on a scan tool but it is next to impossible. As far as the auto hubs they can be a little wierd, with the truck is 2wd crawl under and turn the front driveshaft by hand a few turns in both directions while watching the outter u-joints to be sure they are turning and the front hubs should lock in and you won't be able to turn it anymore. If it just keeps turning and turning the hubs are gone, I would recomend a good set of Warn 1/4 turn hubs, gottem on my 85 and love them.
