Car will not start sit for 10-15 minutes usually will start then. Except on really Hot days. Took it in and inspection found the car has an intermittent loss of spark. 90,000 tune up performed and fuel system service done. Still had issue. New Distributor was installed, symptom was still present. (Old distributor put back in)
Starter, Battery, and Alternator tested. All working.

any idea what to look for at this point?

When it has intermittent spark, test the power supply to the distributor at that time to see if there are any interruption.

Check the main relays.
