Answer
Linda Greg,
A 95 850 has the diagnostic hook up under hood right front corner by the washer bottle filler. When this car stalls check to see if you are getting fuel pressure. I have seen more that once the fuel pump relays go bad. Is the check engine light on when the car runs? If so read the codes, they may leed you to the problem.
