My 2006 Roadking Classic developed an annoying problem today. Whil driving down the interstate the bike just shut off. No sputters or misfires, it just quit. I coasted to the shoulder and the bike started back up when I hit the starter. I proceed to ride about 80 miles and stop for lunch. About minutes after leaving the restruant the bike died again. This time I just squezed the clutch in, hit the starter and the bike fired up, quit again abouth 30 seconds later. I squeezed the clutch, hit the starter again and the bike started. I then rode about 35 miles home with no problems. Any ideas on where to start.
