I'm about to make a posting with a similiar problem.
My engine does not cutout but on Right turns only, my steering locks up bad. I've had pump, EVO sensor and steering shaft all replaced on different visits (all warranted). The only thing that greatly reduced the locking up was when I got a new set of tires, but now it has returned after about ~10K miles of tire wear and is worse than ever. Going back to the dealer tomorrow morning (7/6), if something gets resolved this time, I'll let you know. Let me know of your success too if you get any.
