Why would a 1999 Saturn SL2 with an okay starter only start after it's been sitting for awhile?

A 1999 Saturn SL2 that only starts after sitting for a while could be experiencing issues related to fuel delivery or the ignition system. If the fuel pump is weak or clogged, it may take time for fuel to reach the engine after sitting. Additionally, the starter may be overheating or developing a poor connection, causing it to fail temporarily until it cools down. Finally, a weak battery or poor electrical connections could also contribute to this intermittent starting issue.
