Had a similiar problem on my 08 k-9. Freaked me out. It turned out to be the EHC going out. On my mech's recomendadation (and it worked for awhile) disconnect the battery totally, let it set for 30 min, the re-connect. It lets the EHC re-set. I made it through a riding season, but always had to carry the proper tools in case it happened on the road. Ended up going with wire plus and eliminated the problem totally.
