Usually it does that when you're low on freon. But if you've recently coverted from R12 to R134a, you could be experiece some of the freon leaking. Or, sometimes when the ambient air is too hot, there's not much your A/C can do, so it cycles(turns on/off), so that it doesn't put too much of a load on your engine causing it to overheat. Lastly, with high RPMs or Wide Open Throttle(WOT), your A/C will shut off to optimize engine power/acceleration.
