Sounds like an immobilizer problem. Try pressing [unlock] on the key next time it happens, and try again.

ok i will if that doesnt work ! what does the unlock (apart from unlock thew car) do!

Disables the cars immobilizer for 40 seconds. Normally the little mole on your key comes in contact with the ring around your keyhole and disables it for you, but if the contact is dirty, or bent back so its not touching, it wont happen.

The immobilizer disables the injector pulse when its armed, or atleast it did on VS - I dont know for sure if its the same for VT but its certainly worth a try.
