AC empty and squeaking. Turned car off and 2 hrs later, car would not start. on 1997 Toyota 4Runner

Car turned over at first but put foot on the gas and it quit. This happened 3 times. Since then, it will crank but not start. AC had been leaking freon. This has never happened before so I am at a loss. Any help is appreciated.
