1997 Buick Lesabre Repair Question
Is it the fuel pump, filter??
Could be a hundred different things so you're going to be better off getting a mechanic involved. He will check for loss of spark, loss of fuel pressure, diagnostic fault codes leading to a defective sensor or wiring. Once the problem system is identified he will go through troubleshooting steps to determine the cause of the no-start.

When problem occurred was the temperature gauge showing hot? Check the coolant, you might have overheated the engine.
