Mazda Repair: Mazda 626 stalls after warming up., mass air flow sensor, mass air flow

Question
1994, Mazda 626, 2.0L, 180,000. Recently it just died, had to replace the timing belt and coil.  It now starts great and runs for a few minutes and then stalls.  It will always start but not run after the engine warms up.  Converter was also changed recently.  I have run out of ideas.

Answer
Hi Gail thanks for asking
This is hard to tell without any more detail but this sounds like a possible problem with the Idle air control motor , a mass air flow sensor, Throttle positiong sensor, or just a vacuum leak.
These are all common symptoms of a engine stalling out.
Good Luck
