no start
 

Have 87 chevy wrangler with 305. After it has ran for about 10min it will not restart. I have to let it sit for about 1 hour before it will run again. I have changed the ignition module under the dist cap but that never helped. When it does run seems to have lots of power and no sputtering. Any ideas??

You might want to describe the symptoms.

Some possible suspects:
Fuel tank vent plugged.
Ignition coil with cracked core - once the core heats up the crack expands and the coil quits working.
Corroded or otherwise poor +12v connector to distributor.

To add to Franken's suggestion - include a couple of engine pics. Maybe something will stand out as a potential problem.

I swapped to a metal can style fuel filter recently and the same problem arose. Swapped back to a plastic Wix and it went away. If you live in a hot area, fuel evaporation inside the fuel lines could be a problem.
