'98 740i with 84K. While traveling about 45mph on level ground, engine shut down. Turned out it was the #57 fuse in the trunk that is one of two identified with the fuel pump. #17 under the hood was fine.

I replaced the #57 fuse and the car started immediatly and continues to run OK. Obviously, I am concerned about what blew the fuse. I checked the wiring under the rear seat and found nothing bare. Anyone have any experience with this?
