Any Ideas. The car would start and run like normal but sometimes it just dies. Very intermittent. It could take me miles before this happens. Whenever I check it's fuse #4 (10 amp) that runs to the main relay. Could it be the main relay. I replaced the main relay so far (had a spare) and drove today without any problems but I'm afraid it will occur again. Could it be something else? Anyone else experienced this?
