I've seen all sorts of answers on here but does not exactly sound like my problem. My sportsman has less than 100 miles. It's been doing this off and on since about new. Just got unbearable Sunday. Every once and awhile not ever trip the hot light would come on and I'd go into limp mode. Does not appear to be hot at all. I usually pull the fan fuse/breaker in the box and stick it back in and remove the battery wire no more than 10 minutes. Then everything goes back to normal and ride the rest of the day with no issues sometimes several trips. Sunday it did it within the first 2 miles reset as usual good for another couple of hours. Then it started every 10 to 15 minutes till had to give up. I tried to limp back to the truck and it stopped completely. I pulled the battery cable once more and it lasted another 10 minutes then I was able to limp back to the truck. radiators not clogged, waters full and fan seems to be coming on and off.
