Pax 2 - 10 Blue Flashes

Hey guys -

My Pax2 has been acting odd lately. When I activate the mouthpiece, the LED's will flash pink/purple for about :05, then they flash blue 10 times and the unit shuts off. I had this same thing happen with my Pax Original and instead of warranty I upgraded to the Pax2. Has this happened with anyone else? I keep it crazy-clean, so I don't think it's an issue of cleanliness.

thanks!
