Oy! Computer problems...gotta love'em 
Thanks KYHeirloomer and Dillbert!!
KYHeiloomer, both explanations sound like they could be the culprit. I'll keep an eye on them and see what happens as I take fruit off or as the weather changes.
Dillbert, The pots are a orange(ish) terracotta color. The pots are sitting on a Trex deck, which can get a little hot. The other plants don't seem to have a problem. But if the problem persists for this one plant I'll try moving it to a more friendly location.
The fertilizer I use is a 9-12-12. In the past years I've always had a problem with blossom end rot. The past year I started treating with dehydrated milk, which did solve the problem as time went on. So this year I'm treating the soil with calcium before I had BER problems. So far it seems to have worked well. I'll give some of the other methods you mentioned a try.
Thanks guys!
