Dear Ray Thanks for your description. Is it possible for you to attach a modest JPG drawing of the stove (150k or so) showing the components and approximate dimensions?
It sounds like too much primary air is being allowed to get to the fuel once a certain portion of the fuel has burned. In other words try it again with less primary air. It may be working in the beginning because the fuel is slowing the air flow. Once everything gets hot the thick walls may be conducting enough heat to roast the fuel with no air at all! Hard to tell without a sketch. Good work and good luck experimenting.
