Might be your internet provider. You may have ridiculous upload or download caps. Might want to contact provider. They could be blocking ports after seeing you use them for a long time. Check your Windows or alternative Firewall program and add exceptions or turn it off to see if problem persists. Also check router to make sure it is not your firewalls. Can always put your system outside the firewall into DMZ mode and see if problem persists.
If not its your router. Also check all your equipment when the lag starts. Is your Router really hot? Is your switch or hub really hot? If equipment is hot try ventilating it better. Hot equipment is not running efficiently and a hot switch or router will fk you up. If you are using wireless adapter check your adapter touch it. Is it hot? Again check ventilation.
P.S. I would really focus on DL/Upload caps and Heating issues with equipment. Due to fact this only happens after a few hours, I think this may be most likely culprit.
