after leaving my car running for about 20mins after a small drive i got back in to it a drove down the road i quickly noticed the car had no power but still running fine. the car has done it a few times before when the bad snow was about and in the -8 degrees temp. i put this down to the cold weather. but today it wasnt cold at all. i am just wondering if anyone has had this problem before or hasany idea wat it maybe? cheers shaun
