That meets the conditions it needs to start. Just for kicks check it when hot

Will do, what else could be the problem or is it worth getting a air test done on it if the hot results show the same?

Just throwing this out there, I had the same issue and was getting ready to air test mine and I did an oil change switching from rotella to motorcraft 15 w40 and the problem was gone immediately. Any idea what oil is in your truck?

Rotella now but has done it since I bought it, not sure what was init when I got it but I'm sure it was cheap cause they didn't use for filters either.

Seems to be like I'm losing fuel pressure cause if I cycle the key 2x it fires right up

You claimed good fuel pressure on the first post, but it is possible to not have good volume... or your fuel pressure gauge could be faulty as well. Anything is possible

I would google the 6.0L bubble test and see if you had an injector leaking combustion gas back into the fuel system.

The CTS is my gauge I don't have any others, from what many have told it'd be a waste of money to add another one.
