Tarragator 8104 code 1347-7

Hi All Hope you can help out. I have a 2006 8104 Tarragator that is giving me code 1347-7. Symptoms are sporadic loss of power. We can be going down the field at full power then it will start to die then recover then die again. It seems like a no fuel issue so we changed fuel filters and cleaned the tanks. It will run fine for a while then all of a sudden it will die again. Any help would be appreciated. Thanks
