I have a simular problem with my 2001 Malibu. It seems to enjoy shutting off while I am driving down the interstate (65 -70 MPH) or while driving down the mainstreet in town ( 20 mph ) and time in between. I first had a cam shaft A sensor error and replaced the cam shaft sensor. Then I had a leaking gasket ( the one around the timing chain ), fixed that too. Now it seems that not only is the mystery problem with it shutting off while driving, but it has also given the impression that the fuel pump is going out. Stopped to pick up my son from a game, and it wouldnt start for two days. No buzzz from the trunk gave off the impression that the fuel pump died. I let it sit until I wasnt sooo angry at it. I started it a week later drove it around the block, to work, and around town with out any problems. Other than it still shutting off at its discretion, it ran fine. Tomorrow I am going to get the fuel pressure tester from my local O'fix it shop, just to see what it tells me. Anyone have any ideas?
