Dying in deep water

With the summer heat my bike continues to die in deep water. I do need to pull it all down tomorrow and start checking connectors but I am getting no CEL, No water in the intake, no water in the CVT. Temp sensor on the dash just goes full cold and the bike stalls like it flooded out. Wait a few seconds cranks over just fine and I can pull right out of the hole like nothing is wrong once it figures out what it needs for fuel it seems.

Seems like the temperature shock is flooding the bike out, anyone else running into this? Just curious is all, just did 50 hour checkup with the exception of the valves, which I feel need done because I have noticed that the bike doesnt really have the bit it did even after last weeks bog.

Pond in question just for reference. If I keep the bike up, she’ll go through just fine, but twice this weekend had some people pull in the other side coming towards me and had to set it down on all 4 for a bit more control then she just died.
