Audio Dropout after Idling

Good afternoon,
 
I am having some audio dropout issues when letting the computer idle while I track myself playing drums. This happens almost exactly at 4 minutes on the dot every time.
 
I have increased ASIO buffer sizes as well as the recording buffer sizes which has not helped. If I am recording someone else tracking and I can move the mouse around, this problem doesn't occur.
 
Is this a setting within Sonar, an "idle dropout" or is there something I can change in my windows 10 settings that is causing it to idle out?
 
Regards,
EJ
