Yamaha R6 bjh99 goes out at about 60 degrees

Hi together. Hope to get tips here. My r6 goes out at about 60 degrees and can only start again after it is cooled down.. Fuel is inside and is pumped. Engine ventilation hose I had off. Comes minimal smoke out. Air filter cleaned. Carburettor cleaned. Spark comes to all 4 candle plugs. Think some electronic part is too warm ???? It runs super at the beginning. So from 58 degrees it turns slightly higher and then less … and then nothing more …. I am grateful for tips. Also upload a video and link this here. Greeting from Dortmund https://youtu.be/9uJORHbi09o
