Hi, I have a 2008 500 Sportsman HO Carb. About 6 months ago it had complete power loss. I unplugged the ECM harness and plugged it back in and power came back on. The only issue was I would just turn the key without starting it up and the display would flash hot engine. I just ignored it and its been running great. Yesterday went deer hunting in the rain and it poured all day. I got back to camp and went out to move it and again, complete power loss. I unplugged the harness from the ECM and it came back on but loses power. The display is saying im in reverse when Im in part. Says im in 4 wheel drive when Im not and flashing hot engine. Its freaking out. What should I replace. Thanks, Neil
