I own a 1994 R1100RSL with 32,000 miles. Lately the engine has died on me a couple of times. The first time I was going down a straight level road at about 60 mph when the engine just quit. No warning. I pulled over to the side of the road and after a few tries it started. It seemed to be at full strength electrically. That evening when I tried to leave work it wouldn't start. Again it cranked fine. After several minutes it started and ran fine all 35 miles home. Now I'm nervous to ride it. I started it twice this past weekend in the garage and it ran fine. Does anybody have any ideas of simple tests to try to help determine what is going on?
