Hey there I have a John Deere 650 J dozer today I'm working it came to a sudden stop motor was still running. And flashed this code ecu 91.9 and Sdm 609.9 would not go forward or reverse. Let the tractor sit for about 15 minutes and it would take off like normal for about 3 to 5 minutes and then do it again. Does anybody have any thoughts of what this could be? Or where to start? Thank you
I'll answer on your other post.
