I have a 98 Bonneville naturally aspirated. When cold it starts up and runs perfectly. Once I shut it off and leave it for a bit, it takes a lot of cranking to get it to started again. After it does restart it usually runs rough for a bit, and sometimes will stall when letting off the gas within a few minutes of restarting it. After I drive for a bit it runs perfect until I shut it off again.
