About 2 weeks ago I noticed it was taking way longer than normal for the engine to shut down when I press the momentary engine stop switch.  Normal being 2-3 seconds.  This is an infrequent issue, but the last time it happened it would not shut down after several attempts. I had to finally go to the back panel to shut it down,  and even then it took 20 seconds.  Today I have shut the engine down  4 times and no issue.  Any ideas? How do I troubleshoot this issue?
