I have a well pump. Water work yesterday, not nothing. Flipped breaker nothing. Neighbors house is fine. Any thoughts?

The first thing I would do is ascertain that the breaker had power. From there I would track the power back to the control box. If I had power to the control box I would check to see if the motor overload was open and last I would check the motor windings for a open winding. Good luck, Tom
