What would cause a 1998 Cadillac stall and die at traffic light?

A 1998 Cadillac may stall and die at a traffic light due to several issues, including a failing fuel pump, a clogged fuel filter, or a malfunctioning ignition system. Additionally, problems with the idle air control valve or vacuum leaks can disrupt engine performance. Electrical issues, such as a weak battery or faulty sensors, may also contribute to stalling. Regular maintenance and diagnostics can help identify and resolve these problems.
