I just bought a 2004 f-250 6.0L with 234000 miles. While I’m driving down the road it’ll die, I’ll turn the key off and it’ll start right back up. I was told it was a sensor but don’t know which one.

I drove it again today and figured out that if I pump the throttle while it’s trying to die it’ll keep it going for a couple seconds longer. It’s acting like it’s not getting any fuel. Which is making me think ficm more and more. But the guy I bought it from had the injectors replaced on one side and not the other so idk if that could be the problem or not.

I took it to the shop. It’s loosing high pressure oil. He said in the 16 yrs that he’s been doing this he’s never seen a truck do what this one is doing.
