The rotor is also new.

This morning for example, started perfect, drove for less than a half mile at approx 50mph and all at once the motor died immediatly. Lights, radio, heater, and starter working but would not start. About 10 minutes later tried to start and then cut off again. A couple of minutes later started immediatly and runs good now.

I was alone with no voltmeter so no way to control power.

Now that it has run for a few minutes, I can start and stop the motor with no problem as often as I want. It is just the first couple of minuutes. Has never cut off on me when motor is even a little bit warm.
