Everything works in my new-to-me 2001 Intrigue, except the Hurricane Heater. It runs great for an hour or more but then I get a fault light on the water pump and it shuts down. If I immediately restart it, it will run a very short time, but if I wait until it cools down and restart it it will run for a period of time again. I replaced the water pump and have the same issue. It almost seems like at some point the water gets too hot and the water pump shuts down?
