Mine wasn't exactly the same problem, but I do know that Mike in Yorkshire had the same problems as me and it's as follows.

On first cold starting the car, it fires up instantly then dies within 3 seconds. If you hold the revs on it will run lumpy for 30 seconds and then be fine.

It's a knackered fuel pump relay that causes it. Funnily enough, mine hasn't done it for a while! As soon as it does I am going to bridge the pins on the relay to test it, then go buy a new relay from the stealership.
