waybuzd, welcome to iRV2.com. We are glad to have you join us here.
If you have not checked the main ground cables, I would suggest you do. Check at the battery bank, frame, transmission and motor. You can always add a new ground as you cannot have too many. After that, make certain the ignition switch connection is good and that you do not have a big heavy wad of keys hanging on the ignition key. Good luck and keep us posted.
