2003 2500 5.3 stalling issue Ok this is a express van with a 5.3 and a 4l80 trans. It starts fine and then slowly dies, you can two foot the van and it will stay running. Once running for a few minutes it will stay running until put in gear. Again you can two foot it to keep it running. it will drive perfect until time to stop then it will stall but you can keep it running (again two footing). This van shows NO codes what so ever. Any Idea's Thanks in advance.

Clean the throttle body and TB blade with some carb cleaner. Try to get both sides clean as best you can. Also might want to clean the IAC up a bit. That would be the nearly free attempt at solving the problem.
If that doesn't work I would take a look at your o2 sensors and see what they are doing (or not doing).
