79 304 quits

I asked about the problem I had with my engine just quitting after it warmed up. The most likely explanation was a bad ignition module. For $20 I replaced it and it still just stops running, won't start until 30 or so minutes pass and it will then start and run. I had a bad wiring problem (it burned up) but it was replaced and the car runs well when it runs. Any other suggestions will be appreciated.

 

Coil would be next on the list (if you have not already replaced it).

 

I would check the connectors that plug into the control unit, looking for green corrosion on the tips; the same goes for the connector at the distributor as well as the connector on the top of the coil.
I would then check for spark/12v with a test light or a volt meter and troubleshoot the system.
A remote possibility could be the bulkhead connector; check for corrosion on the pins as well.

 

Just throwing some things out there, Does yours have a resistor wire between the ignition switch and the coil or a ballast resistor?
I have had that exact same problem with ballast resistors and I have had tired resistor wires result in very hard starting when warm to just flat quitting.
