I have a Utilitech JDW 1000003121 deep well pump. its about six years old and is used about 5 months of the year in a summer home. It has started to turn itself off after running for about 45 seconds. It comes back on after about 5 minutes and then shuts off again after 45 seconds. It continues to do this and can't keep up with the water demand. I'm just wondering if anyone might have some thoughts on what I can check or what I can try to get it working properly again?

Thanks, Mark
