I have a 2001 F250 extended cab, 4x4, with a 7.3L turbo. Each morning I go outside and fire up my truck and have to let it warm up for approximately 15 minutes in order to drive the truck. If I don't do this, the truck will literally fall on it's face. It seems like it's starving for fuel. It will bog out and eventually die. Then, I'll kill my batteries trying to get it started back up. As long as I warm the truck up, it will be fine. It only does this in the morning. The rest of the day, the truck fires right up and runs fine. There is no need to warm it up unless I let it sit overnight. Does anyone have any idea what might be causing this? It's extremely frustrating, especially when I'm running late for work. Thanks in advance.
