I got past the v-ecu 'no communication' for now. No yellow warning anymore. So, I can run it in auto mode for about 10 minutes digging and traveling, but then the red warning comes up to say shut down because of engine error. It derates 30 seconds or so later. It has to be left to cool completely before you get ten minutes again. An immediate restart gets you about a minute or less. No codes in the vehicle messages. Any ideas?
