I'm going for the hail Mary here and praying someone has the answer considering the only post I've found is on the gcsaa and left unanswered.

I got a 4100d (obviously) and out of the blue it just started to throw codes. Sometimes the decks will lift up and you can limp back to the shop. Other times you can't do anything except for shut it down and let it sit. Everything points to the ECU as being the problem to me, but I've also read that that is not likely the issue. Toro said it was the fuel manifold or something which was replaced with no luck.
