you could try getting a new radiator or hoses. check your valves as well sometimes they come loose or they get clogged

Yes, A couple of things.
Ignition Module could be going bad. Once it heats up it causes misfires.
Pick-up coil inside distributor could be corroded. Heats up and expands causing intermittent pulses.
Fuel pump could be going bad. Heats up and pressure decreases.

You need to find out if the sputtering is ignition or fuel related.

What things have you already checked?
