I have a 98 seville sts,70k miles, that only stalls in gear,when stopped at a light and only when its raining or damp out,after a couple of stalls and driving for about 25 minutes it will never stall again for the day.No abnormal codes come up,fuel filter replaced ,any ideas,Thanks John

 

Yes, crank position sensors fail. Wont set a code because it happens too quick. Do a search for crank sensor or crank position sensor. Common failure, new ones are a different color and an improved design.
