On my 88 F250 7.5L which is a new crate, has only 15,000 miles on it, recently it started cutting out while driving, sometimes would restart, sometimes would restart after a while, I replaced the module on the distributer as this had been a problem in the past, it still persisted, replaced the coil, fuel filter, and cleaned out the catalytic converter, had more power but then the truck after starting it yesterday stopped, would not restart for hours, got it started and backed back down the street to get it in the driveway and it died again, later it started would run for about 4-5 minutes and then die, restart and then die again, each time shorter, this happens on either dual gas tank. Someone said it could be the intank fuel pump but since it happens on either tank, would you know the problem? In line fuel pump, regulator or what? Electrical? I am lost and can't get to work, we lost our best friend/mechanic a while ago and so need Helpand don't know where to find it! Thankyou!
This sounds like an electrical problem to me. Since you've replaced the ignition coil and the ignition module I would replace the ignition pick up coil. This sits in the housing of the distributor. I know some times you have to take out the distributor and remove the tree to replace the pick-up coil. If you do make sure you mark the position of the distributor so you don't screw up your timing. To remove the tree there's usually an e clip at the end of the distributor casing that you have to remove to slide out the tree. If you do replace the pick-up make sure you clean all electrical conacts. When the pick-up coil starts to go bad it's as if some one turns the key off. Hope I helped.

Okay, definetly a new direction, but the description fits, it would just cut out while driving down the road (sometimes I could just feel the loss of power and it would immediately resume but then sometimes it would completely shut down and I would have to find a quick place to pull off and hope it would start, which it usually would sooner or later, but Friday morning, it quit and wouldn't start for hours, just crank, then when it does start it runs for about 4-5 minutes and stops again, if I keep trying to start it, each time the run time gets shorter. In my Chilton book it has nothing about a ignition coil pickup, is ther another name or can you direct me to some help. I am totally willing to try this and hope it is it. SO it must be below the plate of the distributer inside where the rotor shaft goes down? Thank you so much for responding, I am really in a spot here, Randy

The name that can also be given for it is the pick-up stator or ignition pick-up. The have a crap load of diffrent ones that will fit your truck from advance auto. If you go there they have pretty good pictures abd descriptions of what is what. Some of these pick-up/stator coils are on the fender well (driverside) and some are located in the distributor, I am almost sure that yours is in your distributor.

Thanks, I found a lot of information, still computing it all though and was wondering if this wou; ld shpw up oin a diagnostic as an error? I have to find someone who can press the gear off and back on for me. Since this was a little involved is why I was wondering if the diagnostic would confirm your suspicions about this part? Thank you for your continued assitance it is very appreciated! Randy

I'm not sure if a computer code would show up for this problem. There might be a slight chance.

Well it seems to have cured the problem and at least ti starts and runs, so I think you were right! I just put in a new distributer so save the hassle of having the gear removed and replaced. The distributor was a little different casing so my marks are off a little and it needs some timing now but I wanted to thankyou for your reply and help, I would still be looking at fuel/electrical. I really do appreciate your help, Leave it to a sparky to trouble shoot!
