Observe the inner portion of the A/C pulley while it's on/ turning (clutch portion, actually the compressor shaft)
Is it slippin'/ dragging on the pulley?
If so, maybe the compressor is locking up?
I'm sorta ruling out the A/C pulley and it's clutch mechanism, as you say it only does it when the A/C is on. (A/C clutch engaged)
