Why does my car shuts off while idle?

here's a scenerio, while driving for an hour already on the freeway, weather is approximate 80+degrees, as i come off the exit or as theres traffic jam, i noticed my car will shut off at a complete stop or while slowing down to 15mph. when car is shut off, it'll take approx 10minutes before it will start up again. *note* it only does this in hot weather. i can drive for 2hours at night come to a complete stop and car will not shut off...

i've installed new radiator, fuel pump, and inline filter....so it cant be the radiator or any of that i dont think? what do you guys think might be the problem?

the car is 1968 ford falcon. 289cu 4.7L v8 with edelbrock 4barrel carb

I would try this first, should be less than 20 bucks delivered to your front door.

Designed to help prevent fuel percolation in Performer Series and Thunder Series AVS carburetors exposed to extreme underhood temperatures. Use #9265 with open plenum manifolds such as Torker II and Victors. #9266 features a divided center which is designed to seal the carburetor to dual-plane manifolds including Performer, Performer RPM and most RPM Air-Gap manifolds. All gaskets come with extended carb studs.

Vapor lock might be the cause. Be sure there's no excessive heat from the exhaust system causing the fuel lines to be overheated and check the fuel pump output to be sure it's up to par- especially seeing as how the pump was run w/a loose eccentric that may have damaged it. Be sure the fuel is fresh and not stale or left over from the winter blend.

I'd also want to verify the gas cap is vented, that the rubber hoses connecting the tank and fuel pump to the hard fuel lines are intact, and that the "sock" or screen that's at the fuel tank sender/fuel pick up inside the tank isn't clogged up, that the filter(s) were all clean.
