I have had this exact problem for months.
I fixed this doing the following, at the recommendation of a MS Tech support agent:
- Make sure all updates have been installed from windows update
- Uninstall Surface System Telemetry, checking the box to remove device driver from system
- Install the surface platform installer (https://www.microsoft.com/en-us/download/confirmation.aspx?id=49498)
This will replace the driver for the Telemtry System with something different than has been installed by windows updates. I've had no sleep errors at all since I did this.
