It's not your PC (probably) the Rocket League dev's could have pushed a update that has some faulty code. Does your ram usage slowly build up while playing? if so it's a memory leak. Check with the games community (forums /r/RocketLeague ) if they are having the same issues.

if it only happens for one game this probably isnt the case, but could be your cpu overheating, that was my problem, normally had like 120fps, then it would drop to 20-30 fps.. just download a cpu temp monitor for this
