I have a 2002 ultra that will randomly die due a complete electrical shut down. Just like turning the key off, Took it to a HD shop ran on dyno, could not reproduce. Relaced master circuit breaker, put 500 mi. on in varying lengths no problem. Yesterday, while riding two up, after approx. 100mi. died 8 times in 20 miles? Made it to the shop. Couldn't re-produce , replaced breaker again, and ordered new ignition. Headed for home died again after about 20mi.restarted made home 80 mi. away. Now seems to run rough and not as much power? Any ideas would be appreciated.
