Hello, do you know if this is the early build or later build 6.0L?
If you have a no start when hot you either have a faulty ipr valve or a bad high pressure oil pump. The ipr should make a leak noise when they fail hot. As for the HPOP they won't make any boise when they failed most of the time. The early style HPOP had a failure issue and get replaced quite often
