I was driving down the road and all of a sudden my car hesitating lost speed

Hello, this sounds discouraging as far as described concerns. I'd say that you'll need to do some hands on testing. Base engine is where I'd start. Is this the V6? If so, you have a timing belt that may have failed. If 4 cylinder, it has a chain; if the timing is found to be intact, you'd check to see if the engine turns by putting a breaker bar and socket on the crankshaft. If it turns, then further testing in the starting system is needed, if you won't get a good cranking out of it. Hello, when you say it overheated -- do you mean the temperature gauge went all the way up? Do you mean that the coolant boiled over? If you only drove a half mile, it sounds almost like a stuck thermostat. But it requires hands on testing to know for sure.
