Did you ever check the float level? if the float is set too low the fuel bowl will not fill up as it should. It might run fine at idle and a couple of times around the block. Once you get going down the road at a good clip the bowl drains down because the float is holding the needle partially closed and you get a lean condition that causes the car to backfire and overheat as you describe. After it sits the bowl fills back up (to it's low level) and the car cools off, it will fire back up, run, then it repeats making you crazy..
