After driving on the interstate for an hour the overheating signal comes on and the car dies. The first time it happened I had it towed to a shop and they looked at it the next morning and found nothing wrong. The second time, again after an hour on the interstate, I left the car parked in a lot and returned the next day and it ran fine without showing the overheating alert.

The auxiliary fan and electric water pump are common failure points on this BMW. As previously stated, a shop with a BMW specific scanner should be able to confirm.
