I’ve had an issue with Resaw King breakage as well. I never considered the fatigue from a 14” wheel, but it sounds like a very likely possibility.
My analysis hinged on the deep gullets. That’s going to be a hotspot for strain. In fact, every break I’ve had started in the gullet. I didn’t realize what was happening at first, I’d just notice that the blade seemed to be thrusting (pulsing?) forward as it ran. Turns out the crack in the gullet starts to open slightly and the blade gets a slight backward bend due to it, and it’s visible when the saw is running. The break always occurred shortly after that began.
Makes me think it’s more suited to larger band saws that take 1” and up blades. The tooth geometry looks to be about the same for 3/4 and 1 inch blades, and the 1” blade has a lot more steel to stand up to the strain.

Half of what we read or hear about finishing is right. We just don’t know which half! — Bob Flexner
