1993 Dodge Intrepid leaks antifreeze

Engine problem
1993 Dodge Intrepid 6 cyl Front Wheel Drive Automatic high miles

while driving the car, the engine has died a couple of times, I pulled over and after about 1 min it restarts. Now I notice that there is antifreeze coming out when I turn the car off after driving it. It seems to be at the front of the car at the front of the pan. It is a 3.5 liter 24 valve and hasn't given me any problems until now. I need the car to get to and from a new job that is comming up in a couple of weeks. I lost my job before xmas and things have been tight (I would gladly donate when I start working)any helpful advice would be appreciated! Would it hurt the engine to dump a ton of stop leak in it or would it do more harm than good? Could it be something minor like air in it?
