Have F-350 04 Super duty 6.0 starts finre when cold. After driving for a while and warming up . I'll stop for ten fifteen minutes try and start and it cranks and sounds just fine but it wont start I'll give it an hour or two and once again it cranks right up. Didn't know if it's one of the 6.0 glitches everyone is talking about.

 

Welcome to the site.

This is usually a high pressure oil pump problem. Scroll down a little bit more on the main forum page and you will notice a forum specifically for the 6.0L engine. There is a lot of information on this problem in there.

Here is a link to the 6.0L forum.
