by the sound of it you could have one or both of these problems.
1. a vacuum leak which is causing the car to over boost.
2. ignition fault which is causing the car to die.
1. look in the engine bay and look for small rubber hoses, check all you can find and look for cracks or splits. make sure you check the small rubber hose on the turbo itself.
2. you may have a faulty spark plug, coil pack, HT lead (depending on which engine you have)
1 is probably your boost problem
2 is your cutting out problem
i hope this helps
If the battery cable are not corroded, replace the battery. The battery
is a very important component of an electrical system. Any check engine
lights? 99 models often have a hole burned into the turbo hose on the
right side of the car.
The TCC solenoid in the transmission needs to be replaced. It is under the side cover. It controls the converter to lock up for better fuel mileage. If you want to drive car until you get it fixed you can un-plug the connector going to the transmission on the front of transmission. This will keep it from going to lock up mode and keep it from stalling until you can fix it. Common problem.
alternator gone bad, 100%. as the voltage starts dropping, all the lights on the dash will go crazy because the electronics cannot perform their self diagnostics, as they do not have sufficient voltage.
