Huh !! No change in blower speed with RPM, and no change in air flow with RPMs either ? But try removing the evaporator sensor anyway, since it is a potential source for the compressor cut-off signal. If it turns out to be the cause, the explanation can come later. Everything tested so far has been indirect links between RPM and compressor cut-off, the direct link is still the speed sensors.
