Wow! That's a tough one! Is the only time this happens on turns? Or can an excessively bumpy road also cause this? I'm thinking two things: AC compressor relay (located behind the glove compartment) can sometimes become loose in its socket. Also, the AC clutch's motion is in a traverse direction, so extra turning force could put a miniscule extra force on the clutch causing it to kick out. But if you've got a cluch that is this borderline, whether or not it engages is usually more related to temperature of the clutch, compressor and not turning forces.
Do you have a multimeter and some time? I recommend first determining if it is mechanical or electrical. When I had problems with mine at 150k, I probed the voltage going to the clutch via the connector on the backside of the compressor. I ran a wire inside the cabin to a multimeter, and made monitored coil voltage. That way I could catch it in the act of a malfunction.
[Sidenote: On mine I determined the problem was mechanical (the cluch was just worn out), but I was able to fix it electrically by adding a small booster relay that gives the coil full battery voltage instead of the less than battery voltage due to line loss and relay contact loss. It's worked fine now for 55k, and was a heck of a lot easier and cheaper than replacing the clutch.]
If you prove it is an electrical problem, then that's good....some wiggling of components should yield the solution. Let me know what you find out
