I googled it and found this comment:

“This was the best tool in my shop for a while. I take special care of this saw. It now has some major problems – frequently it will not start. I have to raise and lower the blade guard and move it up and down. There must be a short in the electricl somewhere. As good as I loved it at the beginning – I would not buy another Hitachi product.”

Maybe that’s your problem.

Any chance the male end of the cord is going out? To me it sounds lik a short somewhere or a capacitor is going bad.
I had a remote control car (not the same as a saw I know) and it started only working in spurts. I took it apart and found that a ground had broken
If u aren’t afraid of ruining it a good first step would b to take it a part and check all the wire connections After that you’d probably hav to start testing all the components

Check the cord first after that brushes and switch are next probable (and most common) suspects. After that the condition of the commutator can be an issue as the brake on these saws powered by universal motors short the motor as a generator and are very rough on brushes and commutators. Any spade connectors can become loose over time with enough temperature cycling resulting in intermittent operation.
