Default 99 5.9 losing fuel prime HELP

I put in new lift pump and now I can get fuel up to top filter and get engine to as normal but after it sits a few hours it starts and run 10 sec and dies there is no fuel at top filter and the lower filter will be half full. Need HELP Thanks Steve

You have a leak in one of your lines, might not be leaking fuel out but air is getting in
