Our '04 Bigfoot 60 over the weekend lost about 50% power. It has maybe 4 or so hours on it total. While running WOT it run cut back to about 50% dropping RPM's to about 3500 and wouldn't idle very good. It remained that way till we got it loaded back on the trailer. There were no warnings. All guages looked normal. Out dealer says it checked out fine and can't find anything wrong with it, but the only way to be sure is to take it to the lake and put it under a load, which I agree but they have the nerve to tell me it costs 75.00 for a lake test thats NOT covered under warranty. I think it's a ripoff since they whole rig is practically brand new. At any rate, has anyone experienced this kind of problem before? I don't mind taking it out myself but I know whats going to happen, it's going to run the same way and I'm going to blow a fuse at the dealership.<br />Any suggestions?
