Something is causing the pump motor to overheat and shut off to avoid permanent failure.
The motor is likely failing. It may be a small part such as the bearings, capacitor or the starting switch, but could also be more severe such as the winding itself. You will also want to examine the shaft to see if it is damaged, bent, or the bearings failing or seized. If you are not familiar with testing these parts your best bet would be a local electric motor repair shop to see if the motor can be repaired or if it would need to be replaced. *All of this assumes this is an older/existing installation that has worked properly in the past and is just now showing signs of failure. If this is a new install look at your line voltage versus the voltage the motor is set to accept. If feeding 115 to a motor wired to be on 230 you will also get the situation you describe.

Removing the impeller requires you lock the shaft as you turn the impeller off counter-clockwise. You will also need to check for an impeller screw in the center of the impeller inlet. If a screw is present they are usually left hand thread. Back out the screw first, then proceed to remove the impeller.
To lock the impeller you will have to remove the motor end cover or a cap covering the shaft end depending on which version your particular motor has. Look at the end opposite the pump and imagine a shaft from one end to the other right in the center.
Once you remove the cover you will see a slot for a screwdriver, a flat for a wrench, a hex hole for a hex key or some combination of these. Lock the shaft and spin off the impeller. Some are so tight you will end up breaking them in the process. Simply replace it and the seal. Be sure the motor shaft is in good enough condition to allow the new seal to work properly. If too much shaft material has rotted away the new seal will leak soon after it is installed; you would need a new motor at that point.
