ive noticed on a lot of newer ford vehicles the TCC will slip if the tranny fluid needs to be changed. my boss swore up and down it was a misfire but i checked all the monitors on his truck and none of them had regular misfires. we flushed the trans and it hasnt done it since. also we have done it on many of the trucks that are on the lot along with a few of the cars. might try flushing it and putting in the MERCON V that it PROBABLY (99% chance here) recommends and see if that takes care of it. flush+filter its worth a shot.
