my vt ss had a problem like that, would start up and stall straight away, wasnt all the time tho, but all i did was turn the key to accessories for 5-10 seconds, then all the way off, than tried starting it again, hasnt stalled again since.

Try hopping in, lock your doors and unlock them. Start car. Or put key in and turn from off to acc back and forth about ten times and start. If one of these work it's your keyhead. If not it's in the bcm and expensive as you will need a tech 2
