I just got off the phone with the shop. They said that the wire going to number six was making contact with a hot wire somewhere in the box. They just replaced faulty sections of wire and the car funtioned normally, as it once did. They also said that a piece of metal from a preiously blown fuse may have lodged itself inside the fuse box and made contact between two posts, which most likely led to the problem.

It turned out to be something that I never would have thought of. Again, thank to everyone for all of the ideas which in turn certainly saved me hundreds of dollars in diagnostic time.
