Need help in understanding the issue with the submersible pump


We have a borewell of depth about 1000ft. Recently we have installed a submersible pump. The pump starts well with the starter and pumps water for 10 mins and suddenly it stops working. We see that the starter is tripping and dont see a high current also.

We thought that the issue might be with starter but later checked with other starter and the behaviour is same.

WE are facing thi issue after we ran the pump continously for almost 3 hours with  power failure inbetween. 

What might be the reason for this issue? Has the pump gone faulty? Is it the wiring issue or Is there no water left in borewell?

Could you please help me understand the issue?
