I'm a novice on here but sure need help. My 2004 sportster 1200 custom was running great, stopped to gas up and then nothing, no lights, no nothing, totally dead and unresponsive. Got the trailer to haul it home and when I got back it fired right up, which makes me think the problem may be heat related. Has anybody encountered this and are there any suggestions? Is there maybe a relay gone bad? I'm stuck with this one. New battery and fairly new starter so I'm sure thats not the problem.
