Playback following repeat consistently cuts out after a certain period of time

The start repeat on pg. 84 (Letter E), thru the end repeat on. pg. 86. After the repeat, the playback will randomly cut out on beat 4 of measure 60 of the mvmt. I can't seem to figure out why its happening. I have the play repeats option turned on, as well. I think it has something to do with Muse Sounds, because the crash cymbal, of which I am using another soundfont, is the only instrument that sounds following the repeat.
