At no specific time or under any specific circumstances my immobiliser is kicking in, car starts runs for a few seconds and cuts out, then won't start afterwards. I have to get out the car lock it, wait for the immobiliser to reset about 15 minutes and get back in and starts fine. Fuel pumps are priming and everything.
Noticed I've been using the second key so now have both keys with me just incase it happens again.
Anybody got any ideas?
