WAS DRIVING AND THE CAR JUST SHUT OFF AND THEN ...
2001 Buick Regal

Was driving and the car just shut off and then would crank but not start. So far have replaced the water pump, cat converter, fuel filter, alternator and battery, throttle positioning sensor. Mechanic has done diagnostic test - nothing came up. Car will start and run for 5-10 minutes and then shut off. Noticed a couple of months ago that the RPM's revved between 2-3000 between 50 -70 miles an hour on the highway. Please help.
