After sitting for a few hours,it wants to stall,but then is fine after driving for a few minutes(5 minutes)I realize that there could be a myriad of things,but I'll start with the most expensive-Could the fuel pump be going out?Is it in the gas tank?Thanks.

Your car likely needs some standard preventive maintenace items, such as replacing:

. Spark plugs (ACDelco only).
. Distributor cap, rotor, and wires.
. Fuel filter.
. Air filter.
. Ignition Control Module:

Be sure and check for codes, just to be safe. I doubt the fuel pump is bad. I assumed you had the 6 cylinder engine. Ensure battery is fully charged, plus clean terminals and connections.
