Have an 86 fourtrax 350 that I've owned since new. Had an issue that started last fall where the bike would simple shut down while riding. I'd let it sit a bit and then it would start and run. Happened again this spring. When it occurs I have no oil light, neutral light, headlight or ability to engage the starter switch on the handle bars. The battery is new, all the fuses are good and I have power at the starter solenoid. Another odd thing is when I would turn on the key it would take a 10-15 seconds for the neutral light to come on and sometimes it would be very dim. It almost acts like loose connection or a switch that's not operating correctly, but I have been unable to find either. I replaced the ignition switch a year or so ago with a non-oem switch. Would appreciate any thoughts anyone would have.
