It Could Be A Intake Manifold Leak But Check The O Rings On The Injectors First
SOURCE: transmission ?
The TCC solonoid is bad I have changed hundred of these there is a square coector of the front side of the transmission, this is the connector for the TCC ( torque converter Clutch) it has a tab lock put your finger nale under the tab or a smal screwdriver and lift gently and pull the connector off the car will now drive when you put it in gear but NOT have 4th gear and theck engine light may come on you should get this fixed as soon as possible you have to take off the side transmission cover the TCC is in there only buy one directly from the GM dealer no one else trust me on this, and also change te transmissin filter and gasket while your there.

You need new timing belt and gears. Buicks gears are made of plastic, and become a big glob. Nothing for the timing belt to grab onto.
SOURCE: starting after driving
Most likely the fuel injectors are leaking down. Sometimes, when hot, if you put your gas pedal to the floor the computer will see the engine as flooded and cut off fuel allowing the car to start on the gas that has seeped down into the cylinders. Only solution is to replace injectors with new ones.

Sounds like it might be either the fuel filter or the fuel pump, cause if you ran the tank down, you probably had sludge in the bottom of the tank that you sucked into the engine, you can try using a fuel system cleaner, you may have sucked sludge into the injectors running it, Zmax sells a fuel system cleaner, or there is one called RUN RIGHT, I would try putting some of that in letting it sit a few min then after it sat a few to soak in and break down the sludge, then start the car up, kick your idle up to around 1500 RPM do not go higher then that cause you will damage the engine, try that and see if that works for you, if not then I is probably the fuel pump or filter.
hope this helps.

Check your fuel pump presure. Pump is in the tank. Also try and loosen the fuel cap, the tank vent may be stopped up.
Engine stalls or RPM
fluctuates at idle up and down or dies near idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
