If it is telling the ECM that your engine is cold but it is really warm, it can cause it to run poorly. Usually, if the ECT sensor was bad, the truck would restart after the engine cooled down. I wonder if the cat is plugged. You should remove the 02 sensor from the exhaust manifold and try to start it.

This time it started with an idle around 1500rpm, slowly dropped to 1k, then quickly cycled back up to 1500.

After driving for about 20 minutes, the engine will die while driving, and will not start back up until the next day. I have sat in the car for literally 4 hours patiently waiting for it to start.

If the carb is only overflowing when warm, its possible that the bowl vent on the carb is plugged and causing the carb to pressurize when warm.
