I have a 1993 6.5 turbo after it has ran for about a half hour it will stall,it will start back up but stall 10 seconds later,after letting it sit for a hour or so it will start back up fine.
I have changed the lift pump,fuel filter and oil pressure switch so far does this sound like a injection pump problem?
I just bought this truck with 180xxx on it and I noticed someone has replaced the fuel lines with rubber could this cause a problem also I have removed the gas cap to see if there was any pressure and there was none any help would be appreciated thanks...

 

Thinking you got a hole in the fuel line between the tank and the lift pump. Pressure the tank up to 10 lbs and see if any fuel leaks out.

 

Any updates??

 

Any luck??
