my bike is a 93 Ultra Classic, but this problem from what I have read affects many model's and years of bikes! as far as the loss of electrical power goes, When the weather is hot outside 85º - 90º and I am at a stop sign or red light my bike was losing all electrical power for 10-15 seconds or so, after a while of scratching my head. I discovered my main circuit breaker was opening up from the combination of outside heat and engine heat (30amp circuit breaker located under seat in front of battery on a thin wall of sheet metal, on the other side of sheet metal is my exhaust pipe) I moved the circuit breaker under my side cover (carburetor side) and no more circuit breaker tripping. hope this helps many!
