Gloria, there may be no place for the water to be pumped away from your house. If the pump is just connected to pipes that go a little way away from your house, the water will perculate back down to the sump and will keep cycling this way. The reason that the pump stops is probably because the pump gets hot and there is thermal protection for it so it doesn't ruin the motor. I think that you need to call plumbers until you can find one that will come out. Expensive but so is your furniture, carpets, etc.
