Fuel/ Wastegate problem?

Hey guys. I have a few questions truck has been having a few problems. I have a 2004 f350 powerstroke with 33,000 miles. Alright so the other day on the highway at 65 truck felt like it was starving for fuel pulled off the road and truck died. Waited a min then started it with no problem. Drove to the location and back with no problem. Have been driving it and noticed a loss in power. I have also noticed what almost sounds like an exhaust leak coming from under the hood when at a stop. This leads me to thing maybe the wastegate is having a problem. I was also thinking it could be clogged fuel filter. All 8 injectors were replaced less then 5 months ago so i do not believe they could be the problem. If anyone has any other ideas on the problem i would like to hear them and how do i go about checking the wastegate?

The 6.0 does not have a wastegate. I would check the up pipe or maybe the right side y-pipe and any of the flex connections for leaks.

Alright thank you. So you think this will be something to do with a boost leak?

Well determined the exhaust leak sound isnt coming from the turbo but an intercooler line. A local shop said to start with fuel filters but anyone have any other ideas?

I would start by checking fuel pressure at the test port in the fuel bowl......33000 miles and already having 8 new injectors I would look in that direction first.

Well only 2 injectors were bad but the dealership covered some cost so we decided to just go ahead and do all 8 and start with a clean slate on the injectors. What is going to be the easy way to check that?

when was last time you changed your fuel filters? sounds more like a fuel problem then a boost problem. How full was your tank when it shut off?

I would change that filter on the frame rail asap because who knows when it was done last. Has the it happened more then once? Your fuel pump could be on its way out and just not putting out the pressure it should be. I would hook up a pressure gauge and see what its reading when you feel this loss of power.
