I hav an 04 100 classic with about 30k miles on it. Pretty much stock except for some slip ons. Several times on my last few rides it starts skipping and looses power, barely keeps running. Just pull over and stop , turn key off. and then restart and it will run fine. Its happened on expressway riding 70mph and at 40mph leaving a parking lot. Several other times just climbing through the gears. Never stranded but kind of unsettling. Seems like it may be electrical but have no idea where to start. Any ideas? Thanks for any help.
