PONTIAC BONNEVILLE ENGINE PROBLEM

1992 Pontiac Bonneville • 177,000 miles

Had PCM replaced since for ac compressor to cycle
Car now stalls and engine shuts down, check engine chime sounds
but amp gauge normal as well as other gauges. If turn on key nothing happens, amp gauge at lowest setting
If turn key off, wait 10-15 sec and turn key on to start engine, engine starts and can drive 3- 10 minutes before
it stalls again as described. Had to turn ignition off/on 4-5 times to get home
Wrecker picked up and took to shop, the can't duplicate the problem.
Did notice that ac compressor was not cycling again.
Could it still be the PCM
