Crash after half an hour

My friend has an issue while playing this game.
After around 30 min+ the game suddenly turns black.
All ports seem to shut off and the pc seems to crash.
The issue only comes with this game which is strange enough.
Other games run on Highest setting without crashing or lose of video signal.

-Components-
RTX 2080
Ryzen 7 2700x
16 GB Ram DDR4 (2933 Mhz)
650w PSU

The PC seems to have a power outtage and turning off all available ports to save it from shutdown.
This cant be the cause considering the CPU and GPU arent using 100% and arent close to reaching the power limit.

Changing settings doesnt help at all. Lowest to Highest crashes the game and shuts down the pc.

Other games work fine without and issues and no heavy load in the components.
GPU also doesnt run on max so it cant be causing a power outage.
