Code 36 - Vacuum Leak
Code 44 - Oxygen Sensor Lean (O2) V6
Code 56 - Running Lean Under Load

this is a picture of the throttle body removed from the intake manifold, the circle is the Throttle Position Sensor, unscrew it and clean it with Carby Cleaner

Theft deterent signal, this maybe as simple as a battery in the key going flat, or the contacts were the key goes into the barrel arent quiet touching

Vacuum leak, check all the hoses off the throttle body by switching car on, and feeling for air comming out of a vacuum line or the throttle body it self

and the running lean/oxygen sensor problems, i would only be guessing but maybe the oxygen sensor needs replacing

but to your main question, about the stalling, go here http://forums.justcommodores.com.au/showthread.php?t=6573&highlight=Cleaning+Throttle+body
and also clean the throttle position sensor like noted before while throttle body is off, cheers and good luck
