I think the 'pause' might be caused by not being able to stream the rendered audio from hard drive quickly enough, but that doesn't explain why it only does it with the amp connected as stated by the O/P.

Maybe it does it all the time, but is more noticeable when listening through the amp speakers, rather than the laptop speakers.
