Rough Start then Normal after drive

Experiencing a rough start after I leave my Jeep overnight, but once I start it up and attempt to crank it up again everything starts up fine. I do have a CEL for EVAP leaks if that can cause the problem. It's not doing anything now but I'd like to attempt to fix or diagnose what's going on before it get's worse. Anyone have an idea?

I think I may be experiencing the same problem. Define "rough start"
