This issue is most likely due to an incorrect setup. Kindly review the case set up thoroughly, especially boundary condition input 
values. Here is an example. The run is set for 3500sec but it stops after 20sec.  You find out that the max stop voltage has to be 4.2volts, but in the case set up, under solution options, you've set it as 3.6volts. Since the max voltage has already been reached at 3.6Volts, Fluent calculations will stop.
