2019 KIA Optima Lx, help im stuck
Hello everyone, sorry if this isn't the correct place to post this. I have a 2019 KIA Optima Lx with 119000 miles. Last Saturday when my wife and I were in the dairy Queen drive through, out car just died, no codes or anything, we were able start it back up but it would only run 10-15 seconds then die again. After a few times of this we were able to get it to a spot to have it towed to our house. We borrowed a scanner from AutoZone the next day and scanned it, no codes no lights on the dash. If we let it sit overnight it will start up and run but only about ten minutes idling and it will shut down, again no codes. So we asked around several people we know and they said crank and or camshaft position sensor, they don't always throw a code and are cheaper than a fuel pump. Those are now both replaced and still same issue. I swapped the starter and fuel pump relays and again still the same issue. So I'm just wondering if anyone here has any ideas before I go the fuel pump route. Any help is greatly appreciated, love this car otherwise.
Edit to add that restarting it cranked a bit before starting then dying and after it dies when you turn the key to the on position, you cannot hear the fuel pump prime. It feels obvious but I want to make sure there isn't something electrical that I need to check before replacing the pump
