I just got a 2015 ram 1500 longhorn and I can’t figure out what’s going on with it. It keeps throwing code P062A “Fuel Pump Control Performance”.

The truck will cold start just fine and will start normally until it’s been driven for a hour or two, after that if you wait 15 mins and start the truck it will long crank and then start but if you turn it off and on right away after that it would be fine until you wait 15 mins and it will do it again.

The fuel pump was replaced 13k ago at dealership and I have the diagnostic work order that says it was before giving them 20-48psi of pressure and after testIng they determined it was the pump and put a new one in.

Any ideas what to do?

I noticed it gets worse around half a tank of gas. When it is full it will barley do it but when it gets lower it will definitely do it.
