Answer
Hello Curtis,
Sounds like something shorted out, and blew a fusible link. The one that supplies power to the ignition switch.
If the short isn't found and corrected, it will do it again as soon as you repair the link, but that is what it is supposed to do, rather than melt the wires, so look for possibly a wire dropped against the exhaust manifold and melted through, or a wire pinched in a door hinge area, or under the seat. It will probably be an accessory that operates when the key is on. Any aftermarket stereo systems or accessories?
That "relay" you heard could have been a circuit breaker tripping and resetting.
Electric windows or seat are on breakers I believe, and the windows need the key on to work.
