Check ac belt tension. If loose this can happen.

On some cars that would be normal. The idea is that on full throttle situations you want all the horsepower you got, like when you're passing. On some cars there is a sensor for "low vacuum" (full throttle) that clicks off the A/C compressor until you let off the gas. This also protects the compressor from over revving. But checking the belt tension is also a very good idea. That's easy to do.
