Hey, Scotty
I have a 1993/1994 E-150 with an Inline 6 4.9l engine with about 86,000 miles. It is automatic and seems to run fine nothing seems out of the ordinary but then when you drive it too long it will just shut off also it doesn’t seem to be an overheating problem but it isn’t out of the question.
Thanks, Kevin
probably bad fuel pump
Could be but I dont have any problems with starting or it running before it shutsdown
Also, I forgot to say thanks for your help.
Does it start right back up or does it need to cool down before restarting?
Yes after it cools down it starts and runs. The radiator seems to be working though so I’m not sure.

You're welcome! Put me in the fuel pump camp.
I would bet fuel pump. Stalling at high temp is one of the symptoms of a bad fuel pump. Since the van doesn't seem to be overheating as well. See if you can check to see if there be codes to confirm.
ok thank you
Could be a sensor failing when the engine gets to operating temperature and working again after cooling down. Does that engine have a crank or cam sensor?
Not too sure but I will look into it. Thanks
A quick search indicates that it does not have a crank sensor, instead it has a hall effect sensor in the distributor to trigger the ignition. Possibly that is starting to fail when hot.

Check your fuel filter, too. When was it changed last?
Could be getting vapor lock on the fuel line to. There’s usually some form of insulation on the metal fuel lines, over time it can become brittle, break off or fall off. Especially when the line on a van runs right across the intake manifold. See if your line is naked metal or has some type of insulation around it. It’llbe black, mesh looking or look something like this. They were never naked metal on the E series vans.
On side note some of those also had an issue where the ignition control module would overheat and cause same issue. Get a can of compressed air at a computer store. Office Max etc... if you turn them upside down and spray they blow cold. Nect time it dies, frost the ignition module see if it starts right back up.
