I agree with Cornerpost. The big relays back by the batteries are the usual culprit. When a relay goes bad it results in voltage spikes or momentary losses. This confuses the system and you can get various codes. Also check the connections on the wiring harness on top of the injection pump. 15E is one 34E is common, and 37E is common too. The relay is a 200 amp continuous duty relay, so don't put an "el cheapo" in there. They were pretty cheap even from Deere. I thought I was gonna be smart and put in the Napa version, it was more than from Deere. Hope it cures it, because it's an easy fix if it does.
