Hi, this doesn't sound like a bad catalytic converter this sounds more like bad distributor caps and rotors or possibly a problem with the fuel system losing fuel pressure when the car is turned off. If you only experience the poor running when you try to restart the motor when it is hot I'd get a fuel pressure test performed to see if the system loses pressure when you turn the motor off. If it does you may have a bad fuel pump check valve or a bad fuel pressure regulator. Your description of the problem sounds more like bad distributor caps and rotors since it misfires and dies.
Let me know if you have any questions.
