Default Random Reboots on KitKat (AT&T)

I'm running stock, rooted kitkat with stock recovery, flashed on brand new phone, that I also wiped after flashing. I'm getting several random reboots daily, usually when I get ahead of the phone (swiping too fast, hitting home several times because its not responding). Was this the case on JB? Is anyone else having this issue or can they test by opening apps quickly and see if it locks up?
I have 4 G2's in the house, all on the same software. Mine does it most often but wife's has done it a couple of times as well. Just curious if I should attempt a replacement or downgrade to JB to fix.
