'89 f150 5.0L suddenly begins cutting out
Hi there,
Could someone please tell me where to start trying to find the source of my problem. This truck runs perfectly for awhile (as much as ten miles or so) but then suddenly begins sputtering and wants to die. Sometimes I can keep it going but other times it needs to sit awhile then runs fine for a bit, then begins missing again.
Thanks!

My 89 5.0 did the exact same thing. It would run good but then its like once it warmed up it didn't want to run and would sputter and die. But let it cool down it would start right back up.
Mine turned out to be the distributor module on the distributor I believe its the tfi module. It was replaced and ran just fine. They are common to melting so I was told and cheap ones don't last long. So if you get one from autozone or advanced auto get a good brand not some duralast or bwd brand one

For what you would have in a distributor and ignition module you can just get a HEI distributor with the coil, cap, and button.

Appreciate all replies....
....will try turning distributor to get the module off and trying a replacement. What type of fasteners are holding the unit to the distributor (can't quite tell at first glance)? Also noted that heat is the problem here. Should I use dielectric grease between module and distributor?
Thanks to all.

I would change the distributor all the way out. It's expensive I know . But better then wasting time and guessing parts. My buddys bronco was the same way he could drive 15 minutes then it.would start.crapping out. Put in a donor distributor and wallah problem solved. You could try a junk yard. After ypir truck sputters and dies and you getti spark ? Or.maybe getting weak spark

The first time.....
....I started it after the new tfi it started great and idled better than recent memory (which was already pretty good). Truck drove smoothly for about a mile...then began missing slightly so I headed home. Yes, even after I come to a stop and it dies, it usually starts right up, just runs real ragged and won't idle long.
Thanks for any help.
