My Jeep stalled in 50mph traffic causing a horribly dangerous situation. I barely coasted to the side of the road, and it wouldn't restart. I had it towed to the dealer where I was later told my tone/reluctor wheel had broken resulting in loss of signal from the crankshaft sensor so the vehicle shut down.
