Thunderdock G2 + spectre x360 random disconnection of monitor/usb/lan

HP Recommended
Thunderdock G2 + Spectre x360
Microsoft Windows 10 (64-bit)

My thunderdock G2 with Spectre x360 is randomly disconnecting external display, USB, ethernet.

It is not always in the same situation and it is hard do replicate. It looks that it is not problem of connector or physical hardware issue of USB-C port, because it is not cause by physical movement of cable, or notebook.

This problem sometimes happens when I play youtube video, sometimes when I scoll between outlook emailes, but sometimes it happen without any action on user side. 

I have notebook HP Spectre x360 (13 inches) which has no HDMI or Displayport connector (only 1 USB and 2 USB-C thunderbolt 3 ports), I bought this thunderdock G2 cube to be able to connect external monitor, keyboard and mouse. ,

I had standard Thunderbolt dock G2 120W and because I had this problem, I bought Thunderbolt dock with HDI adapter (looks totally same but second one is on the compatibility chart for Spectre X360 and first for elitebooks). Unfortunately random disconnection happen same way on both thunderdocks (so it looks they are same, but same way problematic).

For example you start work, write email, look on the web page and monitor screen goes black. In some cases within two seconds monitor start work again, in most cases it disconnect also ethernet and usb ports. In some cases help restart, sometimes is enought to wait few minutes and it connect again. It is really random issue, but this thunderbolt 3 connection for external displays and ethernet is really nightmare. 😞

I have Windows 10 64 bit latest drivers (bios, dock firmware, all other drivers). When I tried to troubleshoot I also tried  Intel latest drivers. But doesn't metter if HP drivers or intel newer. Problem is still here. Sometimes ones per day, sometimes twentytimes per day. Sometimes help to disconnect usb-c cable and connect again, sometimes only restart of computer.
