I've got a 2007 Ultra about 20,000 miles. The bike shuts down while riding the motor stops and of course I loose speed, in about a minute or so the bike starts up bye it's self and everything is good again. This has happen about three times now this year. The weather was fine no rain, had not washed bike so water short is out. There does not seam to be any rime or reason as to when it goes out. Any suggestions or anybody else have this problem.
