Area where your left foot rests while you are driving
One of the main causes for a 1998 Buick LeSabre to die while driving is a problem with the computer. The computer might tell the fuel pump to shut off and stop sending fuel to the motor.
Your 2001 LeSabre is rated at 20MPG City/29MPG Highway. I've found this rating to be fairly accurate. I average 20-22MPG when I'm not using the A/C and have measured highway mileage at just a shade under 30MPG. Pretty good for a big car that has a little pep.

I still get 19 in the center city and 27 on the highway with fifteen years on the car. It's surprising how well it does on the highway for such a big, comfortable car.

My 90 lesabre did the same thing. When it cut off after driving I sprayed water on the crank sensor and it started right back up. A buick mechanic told me to do this and this is how I found out the crank sensor was bad!
Either it has a bad ground, or the motor is bad.

I put a new crank sensor in it, and now it runs great!
