Retraction Problem, extruder go away!

[Shijune]

Hi all!!

During printing, between one hour and two hours of printing. the extruder goes out of the model, a few times per layer. more than 6 centimeters without any need.https://speedtest.vet/ https://vidmate.bid/

As it moves, it retracts filament. causing it to cool in the extruder and block everything.

I don't know what to do, it does it with almost all models. I am using Cura.

Any solution? Someone else happens?
