ac compressor turns off under light accel

1994 Jeep Grand Cherokee - 5.2 L V8
My jeeps air conditioning cuts out under light acceleration. Is there an adjustment to make the cutout occur at a higher rpm? Is there a way to bypass the cutout mechanism?What part would have to be replaced to cure this problem?
Many thanks for your assistance.

Your likely being cycled by the low pressure cycling switch. That's what it's there for. Your either low on refrigerant or there is a restriction in the system. Most likely a refrigerant leak. jeeps are notorious for evaporators. Bring you BIG wallet for that one.
