Hello. Chances are it's either the electronic speed control or the brushes. If you can get to them, pull the brushes out, turn them 180 degrees and give it try. If that doesn't help and you're willing to dive in a little deeper, bypass the speed control by disconnecting it and wiring the brushes to an external speed control like the <$20 one Harbor Freight sells.
BTW, 128 hrs is good for the typical router. My 7518 Porter Cable's manual says it should be serviced every 100 hrs. IMHO, this is terrible for a $300 machine.
