2002 pontiac sunfire stalling

[Blackdog]

My 2002 Sunfire will start great but once on the move it will stall out. Fuel pump was replaced 5 months ago as well as the battery, alternator and ignition switch. It restarts right away after stalling but will stall again shortly after. Engine is 2.2 litre SFI.

Trans convertor lockup solenoid is a possibility....

Sorry that I forgot to mention that it has a 5 speed standard.

Do you have a check engine light on?
Has anybody checked idle air control valve?

I'll check the vacuum leak thought as well as the IAC. This suddenly just started, was running just fine the day before then started while halfway to work the next.

I recently removed the factory radio and replaced it with a Sony system. Could the Passlock system be causing my issue or am I grasping?
