I have an 05 f250 6.0. Last week it cut off two separate times while sitting at a red light. I didn't think much of it but I noticed it has seemed a little sluggish on the expressway, but it was still running pretty decent. This morning my girlfriend was running some errands and calls me to say the truck won't start. Wtf? When I get there It starts and cuts off a couple of times then It starts but it's not getting any real power as I'm driving, I could only get 15/20 mph. Got home and it shut down in front of my house. HELLLLLLLLP

You are going to need some gauges that read live data to figure this one out, like the scan gauge II or one of the smartphone apps like dashboss for IOS devices or torque pro for android. They are absolutely necessary for diagnosing problems with these trucks and just keeping an eye on them in general. Have you tried unplugging the ICP sensor located towards the front on the passenger side valve cover and see if that makes a difference?
