I have a deep well for my house. 225 feet deep. The water always stops running after about 30 min. Is there any way to to correct this? What is wron with it?

Are you saying the pump stops or it doesn't pump water? 30 continuous minutes of running the well? What are you watering? How deep is the pump? Sounds like you are running the well dry and would have to lower the pump or restrict use.

Your pump could be malfunctioning. We had a 40+ year old pump in a house that would surge on for a few minutes then cut off. We would run out of water or lose pressure often; we replaced the pump and everything was fine. You might look into that. Hope this helped.
