I figured out my problem....it was hardware. My mounting posts were randomly touching the uSD holder pins.
The crazy thing is, is that U-Boot would detect the card and be able to read it's info (manufacturer, ID, size, etc) but could not read the partition table. Hope this saves someone else a few days of troubleshooting....
