220 is quite on the warm side. It's not hot but its border line. Does the truck start right away when it does this or do you have to wait a few minutes? It may be a safety feature that's automatically shutting the engine off due to its temp. Are your fans coming on?

your truck should only be running about 190° and you need to check for vacuum leaks.

Check the wire connector to the coil, had the same problem and the wires rubbed thru at the connector.
