I have a 91 240 w/130,500 on it. Been running well for the past 6-8 months and my 19 yr. old daughter takes it to college daily-about a 60 mile round trip. Yesterday it was unseasonably warm for upstate N.Y. @86 degrees. She's driving home and is cresting a hill and the car starts revving, sputters and dies. She can't re-start. Calls wife cause I'm @ work. My wife gets car started after it had sat for roughly 1/2 hour during her trip to get her. Wife claims car was making humming noise while runnning. She drives it into parking lot and it dies on her. We leave it overnight,I have her bring me back this morning armed with tools. I do a quick visual check of everything- all fine. Nothing broke,leaking or low. I try starting it, fires right up and I drive it the 15 miles home with no issues. It is only 55 degrees out at that time.
In the recent past the car had some fuel delivery issues so at 101,000, I changed the fuel filter and at 102,500 the fuel pressure regulator. Neither of those was the issue, it turned out to be a bad fuel pump relay which I replaced at 105,000.
Does anybody have any clue to what may have caused this problem? My daughter is naturally hesitant to drive now- NO, let me correct that-she refuses to drive it now.
Thanks for any ideas and help.
