1. A method for operating an engine, comprising:
detecting brake application;
defining a look ahead window, where the look ahead window is at least 20 seconds in duration, and where the look ahead window begins at a time or vehicle location when the brake pedal is applied;
inhibiting automatic engine stopping via a controller according to a prediction that conditions indicative of an operator change of mind condition are expected within the look ahead window, where conditions indicative of the operator change of mind comprise an increase of predicted vehicle speed, an increase of driver demand pedal position, at least partially releasing a brake pedal, and off board conditions.
