Default need help diagnosing problem

took my truck out today 95 5.0l 5speed and it ran fine the whole time then i get back on the interstate and go a mile or two and it missing to the point where i couldnt even get up the hill. still had oil pressure and it was running at normal operating temperature. i tried to see if the inside of my distributor was wet it was fine. it still would start but when i gave it gas it just missed wouldn't rev at all. me and my buddy sat there and looked it over and were tryin to figure out what we were gonna do for 10 or 15 minutes i jump back in and start it and it runs fine i drive another mile or two and it starts doing it again i let it cool down start it up and it runs fine another mile or two down the road again...so i just left and came back about 2 hours later runs fine it gets until it gets to normal temperature and it just completely dies on the interstate i coasted it off the side of the road and it's still sitting there. i called my father inlaw and he said it sounded like one of the sensors on my distributor. i remember reading about them on here but cant remember the name.. i don't know if whatever it is could be the problem. but i need to know what the sensors are on the distributor. And any other ideas what it could be.

The Dist. has a PIP sensor (Stator/hall effect) inside, and a TFI module plugged into it, or remotely connected. I can think of about 10 things w/o breakin a sweat. Do Error code scans. Or be prepared to waste time & money.http://www.handsontools.com/Equus-In...ol_p_5574.html or https://www.f150forum.com/f10/how-re...es-obdi-10907/

welll it's sittin in a random parkin spot off the side of the interstate and if it's the pip sensor i could replace that and drive it home. i didn't have a chance to run for error codes never tried it before but the CEL never came on. i don't really have time or money haha, i just replaced the fuel pump, new msd coil, and new plug wires i can hear the fuel pump kick on it sounds like it's just not sparkin right. but i don't understand why it would only do it once the engine warmed up. Could it be the 02 sensors?

The PIP & TFI module are temperature sensitive in their old age & if you replace one, do yourself a favor & replace the other at the same time. The PIP requires Dist. removal. Some people replace the Dist. as a labor saving measure, but a PIP is only about $12. by itself. You can have the TFI bench checked at the parts store, but if the PIP's pooched, replace the TFI at the same time, or you'll be broke down again in another parking lot sooner than later. Sometimes you can tap the Dist/TFI w/ a wrench, for a temporary reprieve. Good luck w/ that & don't hold your breath. It probably is 1 or the other of these, but if it it isn't, don't say I didn't recommend running Error code scans first. A light is not required to have active codes, including a code for a failing PIP! Your fuel pump relay "might" be throwing in the towel too (or the PCM relay, or both). Run E/C scans or keep your piggy bank handy! Good luck!.........How many things so far? I got more! How big is that piggy bank? Here's some useful info: Before norm. op temp. is reached, your in warmup mode. After that, barring unforeseen circumstances (like a bad ETC sensor), your in ECU closed loop mode. Then the ECU gets off it's *** (or is supposed to) and the sensors & ECU, either improve drivability or make your life h*ll. In fact, here's the whole torrid story: http://fordfuelinjection.com/?p=64

Just because you got 114 and 116 doesn't mean they were bad. Those codes come up when the sensors are too cold, the truck wasn't warm enough for the test. The ICM won't show a code, I'm guessing it's that.

You mean the TFI module?

If you want to get all technical.

Yes, the TFI.
