Shutting off while towing is usually a power problem, not the eyebrow board. Road vibration can loosen a 12V connection, or the voltage drops when the tow vehicle's charge line can't keep up. Check the 12V connections and ground at the fridge, and measure the voltage there while towing. If the power is solid, the 639550 optical board is the next thing to look at, and it's in stock.
