04 Ram 1500 5.7 hemi. Hard start only after an hour or more in hot sun or after refueling. Plus after a refuel it stalls if you don't jump up the RPMs. It has a brand new fuel pump and on this model the fuel filter and pressure regulator are built into the pump. I have code that says small evap leak. I have no idea what is causing this. None of the injectors are visibly leaking but as you can see it acts as though it's flooded

The video is what happens everyday after work except on cool days

 

Install a fuel pressure gauge and check to see if pressure bleeds off when you turn truck off. If yes check my old postsI had a similar issue.
