probably yes, although neither fail very often. i have seen a magnet or some of the magnets come off of the stator, or, probably the most common, is a wire got pulled out of the harness, pinched, or severed.
the ECM is rare to fail on your machine. but it can happen. about the only sure fire way to test the ECM is take a machine with an ECM that you know is working fine, and put that into your machine to see if the problem goes away.
but right now, im leaning on somewhere between the coils and stator.
