I am going to throw out one more suggestion. Try cleaning the choke mechanism! My car had the same symptoms as yours, it would run fine when cold, but as the engine got warmer, the choke was sticking, and the car would start to run like crap! It did this intermittenly so it was very difficult to figure out.. Finally, I sprayed my choke mechanism with carb cleaner, and the problem was solved immediately. Give it a try, it can't hurt.. You could also wire the choke open to make sure that this is not the culprit..
Let us know how it turns out..
