2020 BMW C650 GT MAXI-SCOOTER Engine Problems

I HAVE A SECOND ISSUE ON MY C650GT FOR THE TECH TO RESOLVE. IT MAY BE CONNECTED TO THE FIRST ISSUE THAT I EMAILED YOU ABOUT EARLIER. I WAS TRAVELING AT 40 TO 45MPH, THROTTLE WAS STEADY, ALL OF A SUDDEN THE ENGINE THROTTTLE DOWN TO IDLE AND THE BIKE LOST MOMENTUM. I TWISTED THE THROTTLE EVEN MORE TO INCREASE SPEED WITH NO SUCCESS. WITHIN 2-3 SECONDS THE ENGINE RETURNED TO PROPER RPM'S AND ERROR LIGHTS UP ON THE INSTRUMENT CLUSTER AND REMAINED ON UNTIL I PULLED OVER AND SHUT OFF THE IGNITION. I RESTARTED THE BIKE AND THE ASC LIGHT CLEARED. BECAUSE THIS ISSUE OCCURRED WHILE TRAVELING ON A BUSY STRETCH OF ROAD AND COULD HAVE RESULTED IN AN ACCIDENT I WILL FOLLOW UP WITH THE NHTSA AND BMW OF NORTH AMERICA, LLC FOR FURTHER INVESTIGATION.
