A method of controlling a dual powertrain machine includes propelling the dual powertrain machine by transmitting power from a first engine of a primary electronically controlled powertrain to a first set of ground engaging elements, and transmitting power from a second engine of a secondary electronically controlled powertrain to a second set of ground engaging elements. The method also includes identifying a runout condition of the primary electronically controlled powertrain, and limiting a power output of the secondary electronically controlled powertrain responsive to the runout condition.
