Need some tech help A.S.A.P

A friend of mine who plays Rust can only play it for about 5mins. Then as hes moving he just stops to everyone. But he is still moving from what he sees. He Can go for about 5mins then thats it. I am not sure its lag because its always at the same time. Any help on fixing this would be great!..Thanks!!
