I'm not sure about the 04's but I know the 05's had a problem with the SCT fittings leaking when warm, and having a problem building enough pressure while cranking to allow the injectors to fire.

Hopefully someone more knowledgeable then me will chime in here.

If you had water in the oil, then it's possible that the water has damaged the HPOP and it is not developing enough pressure to start the engine when it's warm.

That's kinda what we were thinking but thought I'd get a few other opinions be fore we change the pump. It runs soooo good when its's running tho.

check the injectors too..they can cause a hot no start issue
