The wireless adapter is... problematic. 

Log files can be found at: C:\ProgramData\VIVE Wireless\ConnectionUtility\Log
In particular check the temps; attaching a fan to the receiver side is pretty much a hard requirement, but high temps usually result in grey/blue-outs rather than hard black shutdowns. 

Connect the headset and find the root device in Device Manager. Disable power saving nonsense on each and every one of the devices, specifically the USB hubs and devices listed after the PCIe interface. Find and select the Vive, then switch the View to Devices by Connection to view to view the whole tree of devices.

Having more than 2 monitors connected can cause problems, try disconnecting one.

In the same folder as the Vive wireless app you will find PCIeGenConfig.exe. Try both options there. 

The stock battery cable is fragile garbage; replace it with something sturdier.

The antenna/PCIe card can die, but usually only results in greyouts or inability to connect in the first place. 

I have finally retired mine after about a year of use; blackout every couple of minutes after 2 hours of use. It has always been unstable, but usually only 1-2 greyouts every 3 hour session. Same with a different fully-charged battery so not a battery issue.
Unless you're moving around /a lot/, I would suggest just getting a pulley system instead; it's fine for shooters and stuff.
