Traveling at 60mph on turnpike pulling long heavy trailer in rain at night with moderate to heavy traffic. Sudden shutdown of all systems. Engine shut off and all electrical systems shut down. Unable to restart or get electrical systems to work. Worked vehicle to shoulder and had it towed to a dealership. Waiting for them to open to diagnose and repair. This mechanical and electrical failure had the potential for a catastrophic incident.
