Check out the Buick Lesabre stalling problem and the solution that was found.
While it is acting up check for spark at the spark plugs.You want to do this after it dies and will not start.If spark is good then check fuel pressure.The fuel pressure should be 48-55 psi with the key on and engine off.Let me know what you find Good luck.
Based on my experience working on LeSabres this is typically caused by one of several different sensors. Unless you have mechanic experience, along with a service manual and the appropriate tools I would highly recommend having it looked at by the dealership or a GM certified mechanic.
It could be anything. Please describe "doesn't start", do you get power to you dash/headlights, etc? Does the starter wind up, and make a high whining sound. Does it crank very slowly, and die. Does it crank normally, but the engine refuses to fire?
