Allow the motor an hour to cool off. Then try to restart via normal method PLUS try spinning the motor by hand. If the motor starts to run normally for a few minutes, disconnect the power, remove the capacitor, and take the capacitor to your local HVAC parts warehouse to have them test it for you. If the capacitor tests "failed", replace the capacitor. If the capacitor tests "good", you will need to replace the motor (replace the capacitor when you replace the motor). Hope you find this to be very helpful to you, moving forward. :-)
