Flow resets to initial state after some iterations

I am simulating falling film evaporation over horizontal tubes. While running simulation for Re 1000 in Ansys 18.0 (Fluid Flow (Fluent)), the flow resets to initial state automatically after some iterations but iteration number continues to increase. Each frame corresponds to 50 iterations per time step. Below are the screenshots for the before and after of such a flow reset.

I am still new to Ansys. Kindly suggest me what to do.
