SP3450H
Will intermttently shut down from full speed travel. Dispay and all functions disabled. Display mod flash a 2-58, Steer module 2-58 and the Traction module 316. (No codes logged in fault history)

This only happens about 2 to 3 times for every 6 to 8 hours of run time. Truck is clean. Batteries that cycle through this truck are in great shape and clean. Connections/plugs at dist board and modules are good... Ayone have this issue that can throw me a hint/clue??? Thanks
