I checked and double checked everything with my multimeter. I did have the line and load correct, had 120v incoming at both plugs, and 120v out on the GFCI load. I jiggled the line with the meter hooked up to the downstream plug and it did not waver. Out of ideas, I boxed up the GFCI and exchanged it for a new one. Problem solved.
I hooked up the new GFCI, installed both outlets into the wall, faceplated them, and turned on the power. The GFCI reset correctly and both outlets have power. I have no idea how a brand new outlet can suddenly quit supplying power to it's receptacles, but that appears to be what happened. If either outlet acts up in the very near future I will be back.
Thank you to everyone who responded. This is a fantastic forum and a great resource to this new homeowner. I have plenty of projects on my honey-do list and I will certainly be back with another brain buster.
