Car won't shut off!!!

Today I stopped to pick up some food and when I shut the car off and removed the key it kept running. Several attempts to reinsert the key and turn it to the off position did nothing, the car kept running. I could shut the accesories on and off but the car still ran. I had to go inside and pick up the food while my 10 year old daughter eyed the car from the restraunt window. I told her to shout if anyone touched the car.. and then cover her ears so the gunshots wouldn't damage her hearing.

I called my mechanic and asked him what he thought, and after we talked, I figured I'd go home and pull the relays for the fuel pumps once I got in the garage. About 1/4 of the way home I noticed that putting the wipers on (the ran real slow??) made the tach fly up about 2,000 rpm. I got to thinking that this is electrical and that maybe the heat, which I had on (and hadn't tried in awhile) might be the cause. I shut the heat and after about 20 seconds the car lost power and fuel, the car was still in the off position. I fired her right up and went home and she shut off. It appears that electrical connections in the heat controls were was the culprit.

Any thoughts??? Do I have a melted wire or short??? Everything seems normal, good power, smooth running, good lights, all accessories function, fanbelt in place..etc.
