GM-GMC: truck stalls, chevy silverado, fuel pump filter

Question
i have a 1991 chevy silverado 1500 1/2 ton 2 wheel drive with 190000 miles, well my problem is when i start my truck after about 2-4 minutes it stalls and it will restart and run good but when i put it any gear it stalls and when coming to a stop it stalls , , ,

now for new parts i put a full tuneup,hipo accell coil,new gas tank,fuel pump,filter,starter,battery,egr valve,new exhaust and the list go`s on , , ,     i have no check engine light on and it runs great going down the road at any speed.   Any ideas would be very helpfull. (thanks jeff)

Answer
Have you by chance had your battery disconnected or had the battery drained in the last while.  Those vehicles are very particular with the Idle Air Control valve and it if its setting gets erased from the PCM it causes all sorts of problems.  Aside from that, I would remove it from the throttle body clean the passages and the pintle on the valve itself and see if your condition improves.
Hope that helps.
