I have had an issue with my 1992 6cyl 4x4 f150. It runs fine for about an hour and then dies. I then have to wait about 15-20 minutes and can start it again. I have replaced the ignition module which is located on the drivers side engine well and also the coil, rotor and distributor cap. All spark plug wires are fairly new also, less than 10,000miles.
I have read that I should replace the distributor as an entire unit but am not sure about this.
Any thoughts?
Thanks

Changing the whole distributor would be easyer? Have you checked the fuel pump relay and the computer relay?

I had the same problem and it turned out to be the computer relay.

I have not looked at either relay, will do that seems muh cheaper and easier. Thanks for the input.

Your truck is probably in a union.
It's entitled to a 20 min break every hour.
Don't force the issue or it will go on strike.

But srsly, it's probably the computer relay.

thats funny I know all about union breaks am going to try the computer relay this weekend and go from there.

Is the check engine light coming on?
It could the PIP in the distributer which should set a code.
