Problem
1. after engine heats up and driving on road, suddenly stalls. restarts, then normal
2. after engine heats up, hard left turn, suddenly stalls. restarts, then normal
3. after engine heats up, in neutral, in the garage, reving to about 3K, suddenly stalls. restarts, then normal

Replaced
1. have 3/4 tank gas
2. replaced front & rear fuel filters
3. replaced ignition coil
4. replaced fuel pump
5. jumpered fuel cut off relay, condition same: relay not the problem

Any checks I can conduct to check out the distributor? ignitor or pick up. I don't want to replace and this is not the problem.
Could also be the carb idle speed/mixture. got to remove the carb to access adjustment and i need a propane test fixture

appreciate any help, suggestions
