Pool pump runs 10 seconds shuts off and comes on a few minutes later and the samething runs a few seconds and shuts off? It's a 2 hp sta rite pump nothing clogging the impellar spins freely any ideas thank you

Is water flowing? Any valves closed?

Yes I have water flow been working great until yesterday full water flow no valves closed

It sounds like one of 2 things...

First, turn off the power to the pump. Then, remove the cover on the end of the motor so that you can see inside. I would then click on the pump and observe what happens.

1- A loose electrical connection that is causing your pump to heat up quickly, and "over-load" is the possible cause. Look for a burnt wire, or a loose connection.

2- You may have a bad start capacitor. On a 2hp, the capacitor may be on the end of the motor, or in a small compartment on top under a separate little cover. Many times, if the capacitor is bad, you can tell by looking. There is a little 1/4" or so, round window by the wires. It has a cardboard-like material in the little window. If the capacitor is blown, the cardboard will be puckered out, or have a hole in it. If it is solid, and still indented it is probably okay. Be careful if you touch the wire leads on the capacitor. They are high voltage, and can get your attention if they are charged. Even if you have the power off, a capacitor can retain voltage.

Also, if you have a volt-meter, you can test the wires coming into your pump. You will have 2 hot wires to make 220-240 volts. If you touch both of those wires at the same time with your voltmeter leads, it should register in that range.

Be careful. If you are not familiar with electrical, you might want to call a pro.

Another thing you could do is disconnect Motor wires, and measure resistance to ground from motor leads, or clip an amprobe around the ground and start, see if during that 10 seconds, is the ground is handling current? Like above work safe.

Some motors also have a high limit switch to detect if the motor is over heating, and shut it down if it does. This switch could be bad. (FYI most motors normally get VERY hot to the touch, making it impossible to determine if in fact it's overheating just by feeling how warm it is).

Sick, you are in luck. Three posters and they all are correct. It might take some detective work on your part but follow their directions to track down the issue.
