Clutch or injectors?

[Benjketsa31]

So im driving along i start going faster on the freeway then my car like drops and has no power right at 4 thousand rpm (doesn't happen all the time tho) i was thinking at first it was my leaking injectors maybe one of them miss fires sometimes. But today i was driving along it happen twice in a row but the second time i tested it revved my engine it revved but did make me go anywhere then i put in my clutch and poped it out and then i had go again. Is this my clutch going and i need a new one?
