Night Vapor engine/prop squeals then looses thrust

I'm a noob here and have just dipped my toe into the hobby for the first time in about 30 years. On day two of my return I have run into a problem with my new Night Vapor. After flying it quite a bit today, I started to hear a chirping sound that varied with throttle setting. While flying it back to where I was standing, the chirp turned into a squeal and then the a/c lost power (still squealing) and descended into the grass. I retrieved it and then slowly advanced the throttle to start troubleshooting. When it just starts to turn, the prop/gears/engine sound fine. At about 10% throw on the throttle, the squeal starts to build and if any more power is added, the airframe shudders and there is a noticeable loss in engine power.

Can anyone point me in the right direction to start replacing parts?
