Was the A/C recently repaired? An over-charged A/C system (too much refrigerant) can cause engine to stall with A/C on. Also have the charging system tested. The A/C draws a lot of power from the engine which also puts a strain on the charging system, if the alternator is weak then it may not be able to handle the extra load.
