NVMe drive not found 15 minuets after shut down

[nortrek99]

I have an HP  Notebook - 15-db0004dx .

According to the manual, it has an entry about available storage listing pci3 and NVMe. I do have a slot and a standoff on the motherboard. 

What happens is baffling. 

I install the NVMe (I have tried four or five different brands with the same result) and it is not recognized in the infamous InsydeH20 UEFI or "HP setup utility." After turning off the machine and turning it back on, it is recognized and allows me to load windows. 

After performing all the necessary updates, and enjoying the laptop's new performance, I shut off the machine. 

Now, if I turn the machine on right after shutdown, the machine boots fine. If I wait for 15 or more minutes, and then turn it on, I get the black screen with "hard drive not found."

If I hard reset (turning the machine off with the switch) the boot process is restored. 

However, If I turn it off and wait for 15 minutes again, I get the same issue with the black screen. 

Any help you can provide would help...I'm baffled.
