Sounds like the loss of power cycle is activated. You may need a tune up. Check wores, plugs, Maybe even a coil is going. Fords do this to give you the power you need. The clutch deactivates to lesson drag on the engone.


Also keep in mind...at WOT (wide open throttle) the AC will disengage. A majority of vehicles do this for 1(more power), 2(less wear on the compressor), 3(less change of over pressurizing the AC system). Some cars will cut the AC in excess of 4k rpms. Most cars will cut the AC if the ECU reports a high engine load(in need of a tune up) or if there is a misfire (again, to maximize performance).
