I`ve a 2007 petrol VRS which cuts out after starting, intermittently!!!!This only happens when warm and only happens for 3-5 minutes after intial start.

Any idea`s??

:'(

Any engine warning lights or other lights on the dash (flashing key for example)?

Worn key?

I had that problem with an Astra. They key was worn and wouldn't make a proper connection and made the immobiliser cut in.
