Narrative:
[In cruise flight] at FL320; #1 pitch trim lever clicked off followed shortly by #2 pitch trim; then the autopilot clicked off. I took control of the airplane [and] had the first officer attempt re-engage the pitch trim levers and autopilot. Moments later the same sequence of events happened again. Instructed the first officer to one more attempt; same thing happened. Third try; I instructed the first officer to just engage the #2 pitch trim system and the autopilot. No avail. I attempted to manually trim the stab with the trim wheel but no luck. The first officer ran checklist. We descended to FL280; not rvsm. Got direct to [a nearby suitable airport]; 40 miles out at 10;000 feet; declared emergency with approach control; vectors around for ILS; made flaps 15/20 landing because gusting crosswinds and a good deal of nose down pressure on the control wheel. Landing; rollout; taxi to gate [with] no problems.
