Drive 6 hours to island park and had a fun day. Sled is base 2020 khaos 850. Sled ran great. Last 2 hours the temp readings became erratic engine cold to 105, but still ran great. Shut engine off and started fine all day. Drove to trailer and went to load and sled is dead. Changed plugs, plugs get a spark. Seem to get fuel but engine doesn’t even turn over, like kill switch depressed. Played with tether and even unhooked it. Have a tss bypass for a 2016 - assume the same and bypassed it. Unhooked hood. Nothing seemed to make a difference. Any ideas?
