ok, have not had time to pull the plug. What I did do was go get some Techron fuel injector cleaner and dump a couple ounces in her. I started her up and she idled fine as always. I rode around the yard and she cut off. Would not start back up. I put the battery charger on and waited about 1/2 hour. Hit the button and she fired right up. After about 45 seconds to a minute the exhaust note changed noticeably. I took her out and up and down the road and everything seems back to normal! WTF?

So, I'll report back as things develop. The exhaust pipe was not glowing and she ran fine during the test ride.

Thanks for the suggestions guys and please, all thoughts are most welcome!
