Does it stall while driving or only when coming to a stop? If while driving, get a new fuel pump relay and check the current draw on the fuel pumps -- if one is going bad and pulling too much juice, it will toast the relay.

If it only happens while coming to a stop, remove and clean the idle control valve and replace the associated hoses if hard and leaking.

Probably the relay.
