Hitting bumps causing power failure
I've been scouring the forums for possible solutions to a problem I started experiencing recently and can't seem to find anything that quite matches...
Yesterday while riding home, I hit a fairly standard-issue bump and immediately lost engine power; slowing very quickly while I attempted to restart. Other electrical seemed to be functional while the engine was dead - I could grind on the startor and even got it running again before I came to a complete stop. I believe I noticed the dash lights and similar were still functional when the engine power cut out. It started back up and promptly cut out again a few times, so I hopped off and took a look. I jiggled a few wires, disconnected and reconnected the plug caps and 2 visible wiring harnesses, and all was well for the rest of my 20 mile ride home.
It happened again today after traveling a bumpy section of road, so I'm thinking the bumps might not be a coincidence here? But I could be wrong. It seems more electrical than gas - but again, I could be wrong. When power is lost, it has cut out immediately and cleanly, and with some in-out-in-out choppiness before dying...
Where should I start checking for something loose or touching something it shouldn't be touching? Any help is greatly appreciated!
