I have a 2007 Heritage Springer with around 53,000 miles. Occasionally, while riding, especially on a hot day, the bike completely shuts down: no engine power, no throttle response and no electrical power. After safely stopping, I will recycle the ignition and on/off switches and the bike will start and run just as if nothing happened. The battery checks good and is kept on a Battery Tender when I'm not riding the ECM has been replaced; all circuit breakers are secure and show no signs of wear; looking at the wiring harnesses and any exposed wires shows no wearing that would possibly cause a short. Fault codes indicate high readings for both the front and rear O2 sensors; these are the only fault codes.

Because I can recycle the two switches and the bike will run normally (until the next time it decides to quit), I feel the problem is an electrical problem rather than an O2 sensor problem. A fuel/fuel filter issue may be the cause but because I can start the bike after recycling the two switches, I am leaning toward an electrical problem.

Has anyone experienced similar problems and if so, what were the cause(s) and fixes?

 

wrong forum!

 

Fastfac - probably best to post your problem in one (or both) of these areas:
