Question
Hi I have installed new rotor, dist-cap, ign-module, coil, check battery connections, car has half a tank of fuel.

It will run for 20 to 30 minutes and than stall. I have checked for spark at the plug after it stalls and there is no spark.
It will start back up after it cools down for 45 minutes.
Once it starts, it will run for 20 minutes or so and stall.

There is no spark at the plug.

Any idea what is going on here? Any suggestions or help is very much appreciated.

Thanks
