Look in the site. there are many cases like yours and mine. It is a sensor attached to the air intake. I am not an expert of this, but it looks like a very common issue

I ended up replacing the the Sensor T-map (70$). An other possible issue is the other sensor, the T-bap, but that was ok in my case. Hope it helps!

Hey!
I have a 2005 sportsman 800 showoing code 45 only. Most common feedback is the wiring harness or T-BAP. My bike and other feedback that thier bikes were stalling/dying somewhat randomely was a symptom. Could operate for a day or a couple of hours and no problem then suddenly it would die. Let set for about a half hour and could go again for a while......or as little as ten minutes and die again. I found that the longe I let it sit, the longer it would run before stalling again. Sems like a heating and cooling roblem that could be wire related...but.....
So, wondering if you had the same stalling issue....should help narrow down the cause and solution.
