my car while driving stalls out and dies only when the temp out side reaches 93-higher degrees. what would make that occur when it is hot outside.
Often it is some heat-affected electrical part in the ignition system, like a crank position sensor or if it has a distributor the pickup coil inside it. Fuel pump relay also.
Do other electrical things (lights, radio, dash) still work when it quits on you?
Yes everything still works. The engine just stall out after a stop and only in extreme hot weather with temps of 922- and above outside.
At that point someone needs to fid out if the engine lacks spark or lacks fuel. The answer will lead to further diagnostic steps, or at least hunches.
