Disable never interrupts an ongoing Outrage, regardless of who is using Outrage. It does stop the pokemon from performing another outrage after its current one ends.
A high base power attack can interrupt an Outrage from a non-dragon-type, but dragon-types' Outrages cannot be interrupted in this manner. As evidence, I cite this from the STAB definition in the DAT:
Uncontrollable Attacks: Pokemon will not be subject to the disruption of Petal Dance, Outrage, and Thrash when hit by moves with greater than 12 Base Attack Power.
Yeah, guys, STAB means more than +3 BAP and -1 energy.
