I purchased a new Ryobi 2 HP Router to put a round edge on my newly purchased butcher block. It made 5 passes and stopped working. This was immediately after my son's Ryobi 2HP router (refurbished) stopped working after only 2 passes. Is this a thing with Ryobi Routers? There was no smoking or bogging down of the engine, it just stopped. We double-checked the plugs and even took off the cover to see if any of the wires appeared "fryed". there was no obvious damage. Again, it was only 5 passes of approximately 42". We kept the depth short to prevent excessive load.
