I got a 2016 Sportsman 570 that stalls out on wide open throttle but will come back alive after 3-5 seconds of deceleration. This only happens when its at operating temp and when it's not happening, the machine runs perfect. No backfires, or lack of performance. When it happens, it feels like the key is shut off. If I keep the throttle pinned, it will cut back on and take off, then die out again. I checked fuel pressure and I'm ~55psi, even while stalling. Also, no codes are displaying. Seems electrical... Does anyone have any suggestions or experience with this? Any input is appreciated. Thanks fellas!

Here's a video clip of what it does. Seems to happen at 5k rpms usually, but that fluctuates a bit. I can't find any posts of people with this specific problem. Thoughts??

So, I've got 2 identical machines. I've swapped throttles, and I'm about to swap out ECMs here in a sec. Problems continue to follow the red one and I'm swapping parts off the yellow one to isolate the problem.
