Answers :

If it does it when idling I would suspect an IAC motor (Idle Air Control). If it is opening too slowly the added air the motor needs will not be supplied fast enough and the engine will kill.

It could be other things also but this is where I would start.
Your a/c needs maintenance the pulley bearings needs to be overhauled
Ac's power drain rest of the vehicle out puts cause its putting strain on alternator and battery
Have battery and alternator checked
Above 12 volts good below 12 volts bad use volt meter with dc current just connect to battery
