My 2003 ultra (stage 1 with a V+H fuel Pak) has cut out a couple of times during a run. So far it has been towards the end of a 50m plus ride. All engine power goes, no lights speedo, gauges, radio as if the battery has disconnected. When I turn the ignition off then back on it restarts. The last time it did this (Sunday) It started straight away but would not initially tick over. When I reclycled it again it ran perfectly. When it last cut I was doing a steady speed, the time before it was in traffic but I was moving when it went, at no time was the engine under any real load nor did it feel particularly hot, oil pressure good. Given it started straight back up I am not inclined to think it is the 40 amp breaker, my experience of these bimetalic breakers on the shovel is they take a while to reset (I could be wrong as this is my first non shovel). The engine light is coming back on after initial initialisation for 6-8 seconds making me think it has thrown an error code but I have been unable to retrieve anything. I have tried the wire loop in 1+2 of the data plug and the efi instructions in the clymer manual (to turn the ignition switch on and off) but to no avail. Dont know if it is connected but it has only ever done it when my misses is on the back, could it be the extra load? She is a lightweight unlike me. Bike is currently running fine but I am worried this will happen again. I have had a good look around checked the usual cuprets (battery, corrodeded contacts etc Any clues?
