2013 1000 melt down?

So this past weekend we were gonna go for a ride, drove an hour and a half to nearest trail everybody got unloaded and we started on our way. I noticed that the radiator fan kicked on relatively quickly but just assumed radiator was a little plugged with mud from previous ride. Well I only made it about five miles at an average speed of around 35mph. We came to a road crossing and the guy in from of me took off a bit faster so I figured I’d jump up on him and then let off. I took off about 1/4 throttle and it shot up to 40mph but didn’t seem like it would pull any more so I gave it more and more throttle all the way to full and still nothing then it started to slow down, it dropped to about 25mph and then the rear tires locked up. I haven’t had the time or more importantly the money to try to look into it yet. This to me is a text book two stroke melt down however this is a four stroke so it confuses me. If the antifreeze truly got hot enough to allow the rings to melt shouldn’t the atv kicked me into a limp mode for over heating?
