I suspect the ethanol fuel was the issue. It does not take well to enginge heat especially when you shut it off hot and try for a restart before it cools down.
I have a driver '47 that I experienced the same issues in. My ignition system was operating 100%. Skip rebuilt coil, 3rd Gen rebuilt distributor, new wires...
I insulated the gas line coming up from the firewall to the fuel pump. Then I installed an insulator carb riser. This soved my issue.
Ford did not do this. I wasn't alive 80 years ago so I can say for sure, however I doubt this was an issue at that time. We should not have to do this to ensure reliability. Ethanol fuel is by far one of the worst things you can run in an engine. Modern fuel injection will put up with it. Anything with a carburetor will not. Not my lawn and outdoor power equipment, antique tractors, old Ford. I keep pure gas on hand at my home for these types of applications. If I'm out on a long drive, I will inevitably have to fill up with enthanol gas. I hate it but have done all that I can to prevent issues.
A good friend of mine recently ran E85 in a flex fuel engine. One week of it caused an entire day in the shop for repairs to sensors. Ethanol is a fleecing.
