Question about Plumbing
This sounds like you have a pressure switch issue.
You can adjust the pressure sensor once you have not load on the pump to stop. If you adjust it and it fails to still shut off than I suggest you replace the pressure switch.

if you have a pump for the whole house you need to check the bladder tank. there is a air valve on the top. Check the pressure with a tire gauge you should have at least 20 PSI this will stop the pump from the on and off thing.
You can compress air yuo can not compress water. thats why the ballder tank. As the pump work to shut off pressure it is compressing air. then when you use a little water the pump does not run until a large about is run then the pump will re fill the system
Best of luck
