Hayward Pool pump shuts off after several seconds

On power up motor is louder than usual; shaft and impeller seem to spin, but motor cuts off after several seconds.  Internal motor circuit breaker (CB) trips and motor will shut off temporarily (sometimes control panel CB will trip).  Input wiring is
  Green -> (GRD);
  Red -> A (LO);
  Black -> L1 (HI);
  White -> L2 (COM);
On power up, HI = 155vac, LO = 232vac; when internal trip takes place, both jump to 240vac.   Start capacitor measures good.  I have primed the pump (filled with water etc).  I can turn the impeller, and the shaft turns when I do so.  Any ideas?

It sounds like you might have a bad phase winding. When the windings go, it's time to replace the motor. The direct replacement motor would be part number SPX3220Z2BER.
