2006 D3LG, fuel issues

New to site, hopefully posted to the correct area. I'm having a fuel prime issue, unit will run for about 15 minutes then lose prime and shut down. I cleaned tank blew all fuel lines out , changed all o-rings , has a new fuel pump and filter and still does the same thing. Once it dies out I take the feed line from tank to back of fuel pump apart, no fuel come out until I blew air through the line into the fuel tank fuel will start to flow from tubing, I put it back together on the fuel pump then will run again for 15 minutes. Even left fuel tank cap off thinking tank wasn't venting still did the same thing
