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

If you are lucky enough to have a fuel pressure gage, it might give you a clue on the fuel pump. Seems that if the fuel was boiling off it would be immediately replenished by the pump.

Sticking float or a clogged needle seat assembly also sounds more plausible, try tapping the bowl lightly with a very small hammer when its dry.

Knowing that these cars all get hot on the track it has to be a fuel delivery problem. If you are not over heating the engine it doesn't should like it's heat causing the problem. Curious that ice seems to help. Purge the fuel lines, tank and double check the fuel filter and pump.
