I got the car new with no accidents but put it in ditch only busted back bumper not bad though. When you're driving every once in a while, it is like stalls it loses power then will kick right in and now when I go to start my car it’s sluggish or it’s like shuts off, but then slowly start to crank then start right up.

Hello, have you had the vehicle looked underneath since the ditch? There are a number of components that could have been damaged. Especially in the rear of the vehicle near the gas tank. There are fuel lines and fuel vapor lines that run on the exterior underneath the gas tank. If any of them got crushed or damaged in any way you will have issues like this. On newer vehicles most of the fuel lines are just hard plastic now, along with the vapor lines (Evap system). Has the check engine light come on yet? and how long ago did this happen? This is a diagram of the Evap canister and Vent valve which has an electrical connector on it that is only plastic as well.
You may want to have someone at least take a look underneath the vehicle on a lift to make sure there are no fuel leaks or broken components.
