2005 Ram 1500 4.7 shuts of randomly while driving. It was doing this originally when I was using the passing gear at high rpm. I would then have to coast to the side completely shut of the engine put in park and it would restart. Of late it has done it just cruising at normal speeds. I have changed the computer, crank sensor, fuel pump (it was bad). I am not sure where to go next. I did see a video on you tube about a non oem coil causing this? Any ideas? There are no codes showing up.
