This is supposed to be the bust of Stephen Colbert, but it kind of reminds me of that scene from Total Recall. Travesty, both the movie and the print.
I've been troubled by this issue from the start. All my big prints have failed in similar fashion, most regrettably the Makerbot plates for Mendel parts. Small prints are no trouble. It seems happen most during the travel phase of the print, as it moves any long distance without extrusion. I've tried a lot of things, including slowing the entire print, travel and all, down to a crawl.
The famous Art of Failure article describes this problem as an issue with insufficient current. I've been playing with the current on the motors a lot. I turn them up until they stutter from too much juice, and I can't seem to make any headway.
I have to solve this, though, because students are going to want to print some largish things.

You are getting skipping; and it may have to do with the heat of your motors. I'm not as familiar with the makerbot as I am with the reprap; but you should be able to turn down the amperage to your motors; recalibrate the steps in firmware and go from there. Also tighten your belts. With a makerbot can you easily add tensionors? They are small and easy to print...
