you know what i had the same problem as you did about a week ago. i was doing about 80 on the expressway and the car just died and would not start. so i pulled off to the side of the road and let it sit for a few and it started with no warning lights on or anything. it has never done it since then. i asked around and i was told that it could possibly be the battery. I have an 04 limited with 41k miles. how many are on yours.
