This is not a camera

Although it has a manufacturer's name of Pentax, I don't think this is a camera. Industrial Machinery may be a better option.

Check the pressure switch. Be sure you have enough water available. Check for a leak. What are you pumping. Is it pumping. I am not familiar with this pump so I am just listing some points to check. If it is a submersible well pump it can develop a lot of pressure.

There's not enough water running into the pump this is why its cutting out , hope this helps

A few more details would help such as model number, is it plugged in etc.

Are you sure the rotor on the motor is rotating freely and getting up to full speed? Did you try running the motor without attaching the housing that actually pumps the water?

it sounds like the switch is faulty take it back to the shop and tell them ok

It sounds like there is a leak in the system allowing pressure to drop.

You probably set the auto power-off for energy saving
