i have a 94 ls auto 154 orig km, when its first started its fine. When i drive around for 10min, turn off the car and start it again, its starts up but then it slowly shuts off. if i wait 5 min, it starts up again but slowly shuts off again after a couple seconds. when i start it again after 10-15min it starts fine and stays on... anyone know what the prob could be?

 

Maybe an ignition issue. Check spark plugs, wires, coils etc...regular maintenance stuff!

 

Also sounds like a faulty alternator.
