help

2011 camaro ss 6.2 starts right up after been parked.after i drive it a few miles when the temperature is normal when i shut off the engine and start back up it has a long delay (like the battery is dieing) and when ut starts on my dash it says check stability track and it runs pretty bad i had my battery checked and the alternator checked there good i replaced my started a few months ago so it’s good. and thoughts of what it could be would be much appreciated
