2013 YAMAHA XT1200Z Electrical System Problems

MY 2013 YAMAHA XTZ1200 SUPER TENERE HAS FAILED TO DECELERATE WHEN I SHUT THE THROTTLE OFF. THE ENGINE REVVED AT OVER 3000 RPM. WHEN IN GEAR IT WOULD JUST KEEP ACCELERATING UNLESS THE CLUTCH WAS ENGAGED, IF ENGAGED THE ENGINE WOULD DROP TO ABOUT 1500 RPM, HOWEVER WHEN RELEASED THE ENGINE WOULD AGAIN REV PAST 3000 RPM. WHEN THIS OCCURRED I TO PULLED OFF THE ROAD, KILLED THE ENGINE AND RESTARTED; IT TOOK A 5-7 RESTARTS UNTIL THE ENGINE SEEMS TO RUN PROPERLY. ON OTHER OCCASIONS THE ENGINE WILL SHUT OFF COMPLETELY WHEN DECELERATING. I WILL BE TRAVELING AND PULL THE CLUTCH IN FOR A RED LIGHT, AND THE ENGINE WILL JUST DIE. WHEN AT THE LIGHT AND I RESTART IT THE RPM WILL BE AROUND 900 OR BELOW AND THEN JUST DIE AGAIN. WHEN GET IT RUNNING I MUST FEATHER THE THROTTLE TO KEEP THE ENGINE RUNNING UNTIL I...

THE BIKE IS DYING WHENEVER I TRY TO COME TO A STOP OR SLOW DOWN. ANYTIME THE RPM'S DROP BELOW 1500 THE BIKE WILL JUST DIE, NOT TRY AND IDLE. THIS STARTED HAPPENING END OF MAY 2017 AND JUST WOULD HAPPEN ONCE, AND THEN AFTER I RESTARTED THE BIKE IT WOULD RUN JUST FINE ALL DAY NO PROBLEMS, AND WAS VERY ERRATIC WHEN IT WOULD HAPPEN. NOW TODAY (8.24.17) IT HAPPENS ALL THE TIME, WHENEVER RPMS GET LOW. BIKE HAS 8100 MILES ON IT, AND IS WELL CARED FOR AND MAINTAINED. BIKE IS CURRENTLY IN THE SHOP AS THEY ARE TRYING TO FIGURE OUT WHAT IS GOING ON.
