115,000 miles. Engine died out of nowhere. No leaks/strange sounds/anything. A few minutes later I tried again and it started right up and drove fine. No strage idle or anything. After a couple of hours I tried again and it would not start. My husband tried a few hours after that and it started right up several times in a row. He then drove it to the gas station, put some fresh gas and a system cleaner in and it would not start at the gas station. Any thoughts?
