Having an issue with an Air dog, I installed the other day, primed it, idled done for like 5 minutes, drove down the road and everything was fine. Then it suddenly just died. Now I bump start it and it'll just die out after 3 to 5 minutes. The tones of the unit change, sometimes high pitched, sometimes a low him. I'm due to change my duty station to Florida here next month, with that said any help is appreciated to help me out. Thank in advance.
I made a video of it but, it doesn't allow me to upload through my phone :/

 

Off hand, the motor is failing when it gets warmed up. That was a typical problem with the unit. Good luck on warranty instead of buying a new unit at near full price. They have been notoriously stingy with the warranty. If you bought it from someone OTHER than AD direct they might treat you better.
