Damn woman! That's a nice rig. I'd kill for a setup like that!
Not sure what the problem could be though. Are your drivers up to date? Video and audio? Try turning down audio hardware acceleration to none in the control panel, under sound. See if that stops it. I noticed my engine sound cuts out when I go high in time compression and then back in when I go back to normal.
Perhaps, when it cuts out and tries to come back in, it's crashing the program? Just a random guess. Worth a shot though.
Hope this helps
