Last night I was on my way home on the m4 on my scooter (model sym hd200). I was in the right lane, wide open throttle doing 115. All of a sudden I lost throttle, It wasn't revving when I twisted. I had been WOT for about 10 mins. I tried to pull over in heavy traffic while I slowed down, but after 3-5 seconds the engine clicked back in and kept running. I was roughly through a quarter of a tank of fuel, 95 octane. What could cause this? is it something I need to be concerned about? I certainly didn't feel very safe losing power at that speed and don't want it to happen again.
