Default 3.0L Revs out at 4500 RPM

I have a 2002 ford Ranger Edge and i've been having issues with it jerking and spitting at 4500+ RPMs. Does this have anything to do with my fuel? I mean i had one blown fuel pump fuse but that was it. Does it have anything to do with my transmission? Its pretty scary going uphill on the interstate because it jerks and it feels like its got a rev limiter on it. It used to not do that. Just wanting to know if anyone else had encountered this problem. Thanks for all the help guys!

I was able to find a few good points just googling and heres what i found...

the fuel filter. Get that changed. Its not expensive and it can work wonders. You might not be getting enough fuel in your engine quick enough to ignite past 4500.
Also, get some injector cleaner.... you could have some cloged injectors.
Change your spark plugs, could also be some misfires.
change your air filters. you might not be getting enough O2 into your engine
check fuel pressure regulators. could have low fuel pressure.
finally.... your car just might be in limp mode. idk how to explain limp mode, but those are some symptomes. do some research.

So does this sound like a good idea before i start?
