Airplanes don't stall because they lose thrust. Power loss does set up a situation that requires action (get the nose down!), but it doesn't cause stalls or spins.
12 (22%) 42 U-FIT Loss of speed Aw. Flight below DMMS not on takeoff results in stall, spin.
In the terminology favored by this author, his Category 11 and Category 12 should, for consistency, both be categorized as resulting from "flight below DMMS."
I can see the utility of the DMMS ("defined minimum maneuvering speed" ) concept, and it is certainly an improvement over relying on Vs. Very suitable for airline use, or here-to-there GA flying. But it does mask the fact that, fundamentally, stalls are dependent only on AoA, not airspeed (or bank, or thrust, or weight, etc).
