Answer
Benjamin,

A couple of things here.  First, check to make sure the airconditioning compressor is not locked up and that is what is causing the engine to die.  Second, if that is not the case and pressing on the gas to increase RPMS will keep the engine running leads me to think the idle air control valve is not working to increase RPMS when the engine takes on the load of the airconditioner.
