Good news, although I do not want to call it solved yet until I get more playtime but it appears I may have corrected the issue. I bought this at the recommendation of other threads I have seen. https://www.amazon.com/gp/product/B00B6ZCNGM/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 I played for an hour last night and an hour this morning and no issues. I even plugged all devices and monitors back in the PC and set the SteamVR settings back to normal for this last hour. AC Router is back on as well. I think the culprit was my ASUS motherboard/ its USB3.0 drivers and ports. The controls feel more responsive now too. I didn't realize I was supposed to be able go to the PC desktop on a center button push and be able to navigate. That never worked before I started used the PCIe USB3.0 device either, just didn't know it. One side note, it does not seem like I can use the camera with this device. At least says the camera it is not recognized. But if this fixed my tracking issues, I am willing to make that tradeoff.

Any updates to this? I am also having a very similar issue with the HTC Pro. The screen will turn all grey after about 5 min of play and will only come back if I reboot SteamVR or the breakout box. The controllers and base stations remain green but the headset goes to flashing green and says "connected but tracking lost". Searching around the forums it seems like a few people have had this issue. I have tried reinstalling SteamVR, disconnecting all other USB devices, disconnecting all secondary monitors, removing and reinstalling the headset USB devices, updating drivers, and even covering my windows. All the same result, the headset will work perfectly for ~5min and then lose tracking. I have a Win10 PC (fresh install), AMD2600X, Geforce1080, 16GB RAM, and a ASUS ROG STRIX B350-F motherboard.
