Razer Blade 15 Shut Down Crashes

I have a 2018 Razer Blade 15 Advanced Model that keeps randomly shutting down, regardless of what I do.

It'll turn on sometimes and run for a while and I can perform some operations then it will randomly just die.

I have tried a fresh install of windows, both from the factory restore stick provided by razer and microsoft.
I originally thought it was my battery and or power supply so I replaced both of those.
I tried a new SSD and also Booting from a usb using windows togo.
Tried using different ram to see if my ram went bad.
Tried apply all driver/ firmware updates. Bios is at 1.07, but it wont update to 1.08 no matter how many times I try. Is there a bootable upgrade ?

I don't know if I have or how to determine if I have some type of hardware failure.

Please help, dont know what else to do.
