Engine Performance problem
1997 Buick Lesabre Engine Size unknown Wheel Drive Type unknown Automatic 158800 miles

I recently purchased a 1997 Buick leasbre on Jan. 25th, 2008. After 6 days, all of a sudden the check engine light came on. I went into the store and the car wouldn't crank or start. The car dealer fixed the problem( I thought) and said the upper intake gasket was blown. Now I have had the car for 7 days after it has been repaired and it will not start. After warming up the car for about a minute the car died and the battery light came on. I tried to start the car again and again it died after a couple of seconds. After it died this time, the check engine light, temperature light, engine oil light and battery light came on. I checked the engine oil and coolant and they were both ok. I even had the battery charged and the car still will not start but you can hear it crank. Any ideas as to what may be the problem?
