Better keep thinking. You have a carburetor and mechanical fuel pump. No relay. The most common heat-related problem would be the pickup coil in the distributor. Next would be the ignition module. These will result in no spark.
When it stalls, check for spark. If it's there, suspect a collapsed pickup screen in the fuel tank. The clue is after sitting a half hour, if it starts right up on the first attempt, suspect loss of spark. If you have to crank a while before it starts, suspect the screen. It will take some cranking for the float bowl to fill with fuel.
