Mind sharing your full system's specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

To me it looks like you have an overheating issue or your PSU is incapable of delivering the necessary power when the system is taxed. All assumptions unless you can state that the system shuts off only when you tax it.
