Blade brake not working 1/2 the time on Hitachi C15FB chop saw
The first picture is the only one I could find of your saw.
All saws are fitted with carbon bushes that contact the armature of the electric motor.
In time the carbon which conducts the electricity wears down, as they disintegrate there are particles of broken carbon connect with the armature giving an intermittent burst of power, eventually the bushes no longer contact the armature and the saw does not work at all.
The next photos show the approximate position of the cover to access the bushes, there is one one each side of the housing.
They usually unscrew and expose the spring plate the bush is mounted on, gently pull this out.
As you can see the bush is worn in a concave shape, and that the wide side is breaking up.
If this is your problem then take the bush and model number of your saw to a supplier or spare parts shop or the hitachi web site to get replacements.
Hope this helps.
If anyone finds this information helpful please tell fixya
