Just to be clear, you start the vehicle and it runs for a couple seconds and then shuts off? Does it restart right away and do this over and over?
If so, does the security light stay on or flash? If not, we need to check the fuel pressure while this is happening. I am thinking you are losing fuel pressure and the engine shuts off. Then you turn the key again and the pump cycles and it builds the pressure and then shuts off again.

However, the more common issue is a security issue so let's start with this info and go from there. Thanks
