Simcube 2 sport is disconnecting while driving

Hi everyone.
We have purchased sim two weeks ago…
All was fine until yesturday…
After the weekend away we come back and experience issue with simcube 2 …while we play it switches of completely…After few minutes comes back on again…
Do we have a faulty unit??
We ha e our usb cables connected to usb hub that has external power…Once simcube switches off itself the little blue light on the usb hub for port 1 where simcube is connected gose off aswell like I would pull usb cable out…rest of the ports r active that we have conect pedals …shifter …handbrake…
I have checked connection to make use all is plugged in…
I wounder how will I troubleshoot this to see where the issue is…
The sim is two weeks old…and we had no issue using it …only started last night…
Thanks.

Update…
I think we had power shortage over the weekend in the village…and power supply wosent restored fully…
Loads of people had issues with diffrent aplaiance in thier houses…that they could use at one time as power usage was to big…
So yesturday I plugged in the power plug that feeds the simucube to diffrent plug in the house and all is working fine sofar🤞…
I presume power supply in the village is fixed and all start working as normal…
