Goldwing

I'll give a little background first, it's my 1st wing i've had it for about two and a half yrs. My first summer everything went great no problems at all. I dont ride much in the winter maybe 3 or 4 times, the following spring broke it out battery felt a little weak, put new battery in and all the rest of the year it occationally dies on me, 98% of the time its at a cruzing speed with no warning at all. When this happens i don't loose any of the lights, or any other items ie. radio, dash lights ect.As soon as i turn the key to the off postion and back on it starts right up, even if i just pull the clutch in and turn the key to off then back on and let out clutch it fires right off every time.I did put in a new fuel filter still does the same thing.The bike runs great, starts up instantly everytime,some days no problems, today i put just over 100 miles on and it did it 5 times.Any thoughts please.60,000 miles
