What are the lights and display showing when this happens? Just got back from a hard enduro race. The bike gave up after half an hour and started working again after long cool down. Everything seemed normal, I could switch maps and all but no movement. While trying to figure out whats the problem, I realized I hadn't heard the fan at all and the start was hard and slow, just that type of stuff where the fan is constsntly on. Not hearing it can be because of other bikes too but who knows?
