Information on motor pump

Motor pump running, but water not flowing in the tank

We have a Suguna Jet Motor Pump which was installed 15 years before. We have a problem, the water flows in the tank for the first two minutes, after that it automatically stops. We have checked with our plumber and the whole 140 ft pipe in the bore well was replaced and the filter changed. But still we are having the same problem. Please send in your suggestions, as we are facing a big problem because of this.
