I have a '89 XLH 883. It normally runs very well. Last weekend it started shutting down just like you turn the key off and then usually starts back up. I changed the ingnition switch and also found a shorted turn signal flasher and fixed that. It still does it and I don't know what to check. Could it be the electronic ignition going bad. Anybody else experienced this problem? It seems to only do it at high rpm. Cruisin the side streets it runs fine. freeway speeds it starts acting up. Any help would be appreciated.
