I have 56,000 miles, and regualr service, it is a 2004 coupe, The engine just stops, everything else runs. when I try to restart the car nothing happens not even a click, just the engine fan comes on. If I leave it and come back (pushed to the side of the road) after 30-60 mins it fires up and off I go. A few times it has even died while driving down the hiway. Same thing wait 30-60 mins and off we go. The Dealer says nothing is wrong.
