While driving at approximately 25 mph, my 2003 limited Toyota Sequoia 4wd vehicle lost power, cutting the engine off in the middle of the road. Placing vehicle into park, then attempting to restart vehicle would not result in restart of vehicle. Had to have vehicle moved out of heavy traffic manually, then towed to Toyota dealership. Dealer found efi fuse number 1 blown, replaced, fuse blew again at dealership, replaced fuse a 2nd time and the vehicle hasn't blown the fuse since (a couple of days later). Dealer noted they do not know why efi fuse blew either time.
