Radiator hoses will wear out and collapse due to the vaccumn affect of the water pump. If any hoses look sucked in, replace them.
Other thing that comes to mind, mineral build up from using tap water will clog the radiator.
My first thought was the radiator cap as well. Go ahead and replace the thermostat, hoses and have a radiator shop clean/flush and pressure test your radiator. It's not expensive if you do the work yourself.
