27" Studio Display randomly turning off with 13" MBP M1

I have the new 27" Studio Display connected to a 13" MBP M1 and the display will randomly tuned off 3 or 4 times within a few minute period. I have a screen saver which kick in normally, and power settings are all ok. The MBP is closed which has caused no issues. I have True Tone turned off.

No application in particular is causing it, it happens in all different apps.

The screen just goes power off black, sound stops, for around 1-3 seconds, then you see it come back on and about a second later screen continues as if there was no issue, no reboot or error on the screen.

Power is connected, no arcing sound when it turns off, other items in cable extension remain on so not a power input issue.

There seems to be no way to report a fault or ask a question on Apple Support for these monitors, nor can you select a studio monitor as a device to log this against.

Anyone had similar or got any ideas?
