turns on fine and stays on for about 10 minutes then turns itself off. It will not turn back on until after it cools, I guess?

have the voltage of the regulator output measured, start from the diode right after the chopper of the main regulator with the 200v capacitor near to it. whatever voltage you get will determine the status of your horizontal deflection circuits. if no voltage at all check for a shorted horizontal output transistor. if you will have a reading of at least 120V have the entire pins of the flyback re-soldered, and check for cold solder joints. if you will be getting a reading of 80V you have a partially shorted flyback transformer.
