House Trained Dog Going In House?

I have a five year old Beagle mix. She is completely house trained, and has been since being twelve weeks old.

She started pooping and peeing in the house in the last six months, but only if she's out of her crate. If she's in her crate she never goes in it. If we leave her out then she'll poop and pee in the same spot within a foot of each other, even after we've let her out. She can go like six hours in her crate without an accident, but we can let her out of her crate in the am, let her outside, then let her have free reign of the house when we go back upstairs to get ready for an hour, then we find our presents downstairs.

It's always the same spot, which makes me think it's a territorial thing. I don't remember our other dog ever going there. The Beagle is such a pleaser. I don't get why she's doing it. Someone please help!
