by cuts off do you mean gos to your defrost or floor vents?

if so its a vacuum issue, check all vacuum lines, your canister, and theres a tan vacuum line on the pass side above your blower motor that is problematic and should be inspected for cracks and repaired if damaged,

other then that you could be low on freon or if your going WOT then the puter is supposed to kick the a/c off

You need to replace the check valve on the vacuum line under the hood (IIRC), when you're pushing down on the throttle, your engine vacuum is decreasing, and the check valve that is supposed to hold the vacuum isn't and your air is being redirected.
