I don't think so F3G.
Stall is only a function of AoA, so by definition if you loose IAS (or better put as loosing TAS), then to maintain height you must increase the AoA to increase the coefficient of lift (CL) to maintain the lift = 0.5 * rho * V^2 * CL * S equation (as all other things are assumed to remain constant).
V=TAS, CL is a function of AoA and wing characteristics, S=wing area and rho=air density.
