My g2 will crank and run good but it will completely shut off and throw 2 codes. Codes 114 and 115. Codes say private network communications. Anyways once it does that, i can put it back in neutral and it will crank right back up and fun fine for a couple minutes and then completely shut off and throw the same codes. Had a mechanic replace all the neymar wiring and didn't fix it. Has anyone else had this problem and if so, how did u fix it?
