I have a 1999 Sebring convertible with a 2.5 Litre V-6. The car runs
fine but at random times the car is completely dead when the ignition
key is turned on, or it cranks the starter very slowly and then goes
dead.  The next morning the car starts fine. The alternator and battery
are new  within the last 2 weeks. I brought the car to a mechanic who
checked the starter out as okay but the car would not act up while he
has looking at it so he couldt get a computer diagnosis on it.  He
suggested maybe oil seeping from the valve cover gasket dripping on the
starter may be a possible cause. Any ideas?
