Car won't run in Az......

Thanks Bob. My first step will be a phenolic spacer....if I cannot find one locally, so far I have only found aluminum ones, I will machine one from wood to see if that solves the problem. The engine temperature runs around 90-100 Celsius, so the motor itself seems to stay cool enough. The issue is the car will die while driving, 30-40 mph...up to this point I have been able to coast to a safe spot to let it cool down. With a bag of ice dumped on the manifold I was able to drive it all the way home with no problem. Without the ice it would have died at least a dozen times considering the distance.

I tend to start with the least glamorous, how old is the fuel filter? It also displays fairly typical traits of a clogged or clogging fuel filter. It may be that it is dying because the fuel isn't getting through the filter. After it dies, the pressure is still in the system and gradually works it's way through into the carb. If the filter has many miles on it, I'd change that first.

Could be a red herring, but maybe not. Tonight, before you go out, remove your air filter and with your hand move the throttle linkage back just as if you were stepping on the throttle pedal. Look down the primary side of your carb and see how the accelerator pump squirts gas out just like a little squirt gun. Then run your car and, when it stalls and won't start, do the exact same thing and see if you see the little squirts of gas coming out. If you don't, then I'm on board with Woodz428, or there's always the small chance of a sticking float that shuts off the gas when it gets hot.
