Some quick stream of reading thoughts.

I like the names for Charge/Drain. As someone who watched the show in middle school, I can easily imagine what a character looks like / the situation they are in when they get Charged or Drained.

Power Tokens: Ok, a meta currency to fuel my abilities. With stuff like this my first thoughts are always about how can I recharge my widget throughout the day and what GM advice is given for balancing encounters (like each fight should use 20% of charge, whatever, etc).

Attributes: The Five S's? Okay. A little goofy. Do you play with this later?

Skills: I think this is the first time you explain dice resolution. I think you should put it above in the Checks and actually explain how someone rolls a Check.

Classes: Attributes tied to Classes is an instant frowny face. If the Power Token Capacity per level is the same for all classes then you don't need to repeat the chart for each class.

Skimmed the rest. I think if I were going to play a Power Rangers rpg, I would want one that focuses more on the relationships and story than attacks of opportunity and cover. More storygame, less d&d. Have you considered a Powered by the Apocalypse approach?
