Not allot of info Mr. Vogey but if I had to guess I would start with a possibly dirty evaporator coil. Possibly a dirty filter or filters. Could be low on Freon.
All or the above suggestions involve the evap coil as what you describe could be the result of the coil freezing. You wait a while and it thaws and starts working again.
Good Luck and keep us posted please. "Q"
