94 E150 Will not start or run after engine is hot
I have search through posts and found some info on this, but couldn't find a positive cause. This is my Dad's van, 94 E150 Conversion w/351. After it gets warmed up/hot, it doesn't want to run, nor restart. Letting it cool down will allow it to run again. He has changed the fuel pump and filter.
Now I have read on various threads that the TPI / ICM that is in the distributor seems to be the culprit. Any thoughts? I haven't looked at his van yet myself, but I will be soon. Does this van actually have a distributor? I thought being a 94 it would be a coil pack/electronic.

Next time it happens, check for spark. I had a similiar problem with my '89 e-250, 5L. It seemed like vapor lock so I thought it was fuel related. After fuel pressure checked out okay, the next time it stalled, I checked for spark, nada. Removed ignition module and had it tested at two different auto shops and it checked out okay. Replaced the ignition pickup without success then the ignition coil, nothing. Finally went back to the ignition module, replaced it and problem solved. Good luck!

Ignition module will not be your problem. Ford fixed the ignition module problem in early '92. Don't rule out ignition components however. when it refuses to start, pull the primary ignition wire, and check for spark. If it is produceing spark when the van refuses to start, you can likely rule out any ignition related causes. My guess, is it is vaporlocking. Check the fuel pressure, and check it again when the engine is hot. Another likely culprit is the ingnition coil. Check the resistance in the coil after the engine has warmed up, and see if it is within specs.

I have been through the same thing with my 94 e150 5.8L conversion. I have replaced everything and I am now down to the Cats. I ordered the replacement which should be here tomorrow. The thing that I finally noticed the last time it stopped running was that the power brakes stop working while it is starting to act up and run rough. It has to be the converters causing back pressure or I am at a total loss.

I wouldn't rule out the ignition module on a van, although the other suggestions are good. The fix in '92 was to move it from the distributor to a location just behind the battery in the drivers side fender area.
The problem they were having with the distributor mounted units was heat related. The van's engine compartment is tight and hot with poor air flow. I think they still get hot in the new location in the vans.
I had the same problem several years back, but nevr got further than checking the fuel pressure before it would self correct and leave me guessing. It hasn't done it in several years now and I didn't fix anything.
