Question Won't start when warmed up

03' 6.0 won't start when it gets warmed up. Turns over fine, just won't fire up!! Starts fine when cold. Drive it 20 miles or so, shut it down and it won't start back. Wait 10 minutes and it will start after grinding the starter for an extended period. Anyone know what's goin on????? Thanks

High pressure oil pump. There are some seals that like to go south on this, and they are located under the drivers side valve cover IIRC. Its pretty common, but I'm no tech either, just from what I've read here for three years

Could be the STC fitting on the back of the hpop. Or could be the IPR

I agree that it sounds like the HPOP, branch tube, or STC fitting. Mine had similar symptoms and all three were replaced. Knock on wood, no more issues.
