Momentarily cuts out at motorway speeds. Happened three times yesterday on the motorway. I had done about 180 miles that day on the motorway. Happened just before a fuel stop and just after.

Anyone had this happen?
Bike has done 12k miles.

Also; anyone had issues with rear wheel bearings?
Mine failed last week and I had to get them fixed in Germany. Still made it to the Elefanten treffen though
