Help! Problems with Cubase LE AI Elements 7 and Guitar Rig 3

So i wanted to record some tracks tonight with my bass guitar using Cubase LE AI 7, Guitar Rig 3 and Steinberg UR22 audio interface. I noticed something while recording - i got some strange hickups from God knows what that causes my track to stop recording. The hickups last about half a second and occur every 2-3 minutes. This is kinda strange for me because that never happens when i use my UR22 and Guitar Rig 3 on stand alone, whats even more strange is that i had tried recording using the same exact settings some 2 months ago, had been recording for a couple of hours and no hickups occured whatsoever. Does anyone have any suggestions why this may be happening? Appreciate the help
