"problem with a crank sensor breaking down, the sensor would behave normally when the engine was cold but once the engine got hot the sensor began breaking down under load and causing many of the symptoms you describe. This was overlooked by many mechanics as the engine ECU had not identified the sensor as bad, and after all how could the car run with a bad sensor right? Once it was put on a scope with the engine hot the sensor break down was obvious. Not sure if your crank sensor is inductive pulse or hall effect but if you can get it scoped or even just swap it for a known good one then at least its ruled out. At this point you need the help of a decent tech with good test equipment as all the best will in the world from us is no match for good face to car diagnostics guy that knows his stuff! ?"
