I was driving my 1993 grand am se down the free way and lost all power but not the lights or electric inside the car and now it won't start

Probably lost either spark or fuel. First try some starting fluid into the throttle body (take off the big air boot) and see if the engine tries to run on it. If it does, you need to see if the fuel pump quit working. Best is to check fuel pressure-autozone and others rent or loan fuel pressure gauges. If pressure is not there with key on, likely a bad fuel pump. (you should hear the pump turn on for 2 seconds when turning the key to on, not start-this will pressurize the lines up to the fuel rail and to the injectors. Listen for the pump to turn on.)

If you have gas up to the engine, and the starting fluid caused nothing, check for spark. Buy a spark tester from a parts store and check for spark on 2 or 3 spark plug wires. If no spark, the ignition system went out. This is often due to the Crank Position Sensor or the Ignition Control Module.
