J, These are always tough to diagnose. Do you have power to all other systems when the engine dies? If the power draw through the circuit breaker is more than 60 amps it will pop the breaker. It will reset after a few minutes. If this happens the breaker will tend to get weak and start popping with less draw. I have had the unilite module fail at random times. Generally heat related. I guess the other thing to check is the connections and the terminals. I haven't had a problem with the length of wires.
