Hi. My '93 2.1 starts and seems to run fine - till it warms up a bit. Then whether idling or driving, it will stall. It will not restart until it cools off. Then it repeats the same thing. Max runs for about 20 minutes.

I replaces the mass airflow sensor cuz it is so easy. Have gone no further yet. Appreciate the help.

This is a common symptom of a failing crank position sensor. I would check that first.

Once everything is out of the way, removing and replacing the CPS is not too difficult. Test it first though by manually turning the engine and measuring the output of the hall sensor.
