It looks like that Xorg's power managements kicks in. Can you try disabling Xorg's PM by adding the following to you /etc/X11/xorg.conf:

Section "ServerFlags"
   Option "NoPM"
EndSection

Note: if you already have "ServerFlags" section, just add Option "NoPM" there.

This may workaround the problem for you.
