06 LT 2.2 losing power to fuel pump

I replaced the fuel pump about a month ago due to cracked fuel line. Now the car will start and run fine while the engine is cool. It will run fine at operating temperature until I turn the engine off. At that point the fuel pump will not prime with key on. Once the car sits for a while, it works again. Tried replacing the relay, that didn't work. Not sure what to check next.
