Can an overpressurized A/C system cause the compressor to kick off?

I think that may be what my problem is.

I thought I had a bad fuse first but that day was the first very hot day around here.

I checked the pressure and it was over 100psi.

I also noticed sometimes when I revved the engine high the A/C would temporarily stop cooling.

If not, what else might I have going on?
