Roger,
Have you checked your engine coolant temp and Intake air temp sensors and or their wiring? If one of these two sensors or their wiring was faulty your engine would behave as you described.

    Hi - the engine temp guage approached 220 so I knew I had to shut it down before the alarm sounded. Haven't checked the Intake Air Temp Sensors. What do I look for or, how do you test them?

    Have you removed the thermistat? If not you may have debris in there or a faulty thermistat. I would pull it and swap and see.

    You may wish to do a compression check. You say runs on 5, not to scare you,but you may have a blown head gasket, ask me why i would say that
