Engine intermittant `cut out`. HELP. Not had the car long, my mechanic is stumped ? Starts and runs beautifully, then after stopping (at traffic lights / junction), just cuts out ?? Nothing obvious, checked all the forum threads, but can`t see one to match. Other days it wont do it. Usually after/during short journey. Once it cut out whilst I was driving. It used to start again after 5 minutes or so, but the last time, it wouldn`t start at all for days. When it happens, turns over fine, but no fire up. Could this be electronic / fuel cut out / Now it is with mechanic and starts all the time !!! typical. What do I check ? he cannot find any faults......Please help.
