Might have something to do with all of those pauses you've got sprinkled in the code. If the pauses don't line up right (the moon, saturn, mars, etc), one part of the project, either the master or the slave, misses a reception at one time or another, and/or gets caught in the middle of one or the other...basically a sync'ing issue.
