My 2006 5.7 Hemi Charger will be runing along just fine then all of a sudden just loose all power. This happens at freeway speed or just taking off from a stop. It has happened with the engine warm or cold and on hot or cold days. It might happen once or twice one day them not for week or can be a consistant problem for days in a row. It has just began dying at an idle as soon as it's put in gear. I just replaced the crankshaft and camshaft position sensors and it fired right up and purred like a kitten - sounded better and felt smoother than it has in quite a while. Unfortunatly it still dies within between two and twenty seconds after putting it in gear.
