After driving several miles on freeway, the engine dies when exiting on the ramp before coming to a full stop. Dealer diagnostics do not reveal a problem. This has also happened after driving a couple of hours when approaching a stop light.

Hi hendersa,

Seems the idling system is erratic. Get the throttle body and IAC cleaned and retest.
