I would be worried about the engine. if it actually quit on you thats not good. (like you didnt know that right? lol). sounds like there may be an air pocket in the cooling system. what type of fan are you using? how many miles on the rad?

Yeah, I'm worried about the engine. The radiator is a 34 inch I bought new last december when I put the 05 up truck e-fans on.
