We tried the ignition module advance tested it 3 times. Still good. Any other suggestions?

If it's stalling after warmup, suspect the pickup coil in the distributor.

Coil and ignition module are both still good. What else should we look at?

Hi 88, To clarify, this is not the ignition coil that creates the spark. I'm referring to the pickup coil next to the shaft in the distributor. It's pulses are what triggers the module to fire the ignition coil. In particular, check the tiny wires attached to the coil. If you can catch it immediately after the engine stalls, unplug that coil and measure its resistance with an ohn meter. Usually it will measure open circuit when it gets hot.
