Speaking of model, what is the make and model number of the fridge?
Most fridges are stopped at least once every 8-12 hours (depending on manufacturer) for about 20-30 minutes. This is the auto defrost cycle in action.
You may have to determine if the "pulsing" was the evaporator fan or the compressor or both. The evap fan should be operating as long as the compressor is running except if you open a door. Then the fan should stop while the compressor keeps going. You don't want to blow all the cold air out of the fridge with the door open. The fan should start again with the door closed.

If it was the compressor that was pulsing on and off it might be the start relay or capacitors (again check make and model) that might be the problem.

If it was the compressor that was pulsing on and off it might be the start relay or run capacitors (again check make and model) that might be the problem.
It may also be that the defrost timer (if it has one - it may be the control board that controls the auto defrost - depends on the make and model) could be faulty.
Sorry to be so vague but more diagnosis may have to be done to narrow down what is happening when the problem occurs:
Is it running in normal mode and this suddenly occurs for no apparent reason?
Has the auto defrost mode finished and the compressor cannot start properly again?
Has the set temp been reached and the compressor/evap fan have been turned off and then when the temp rises does the compressor start again OK or not?
