Avionics shuts down after a few minutes of flight on King Air 350

Hello, I wanted to let you know that there is a bug on the avionics in the King Air 350 plane, as after a few minutes of flight, everything shuts down, I also tried other planes, and everything works, I tried with mods, with custom liveries, and even a fair game, but it doesn’t work anyway. I am attaching photos. Thanks
