You've had a fight on your hands with that truck. I think I would start with the IVM, battery, and then alternator with my troubleshooting. Doesn't cost anything to check them.
IVM or why my engine runs sluggish??? N62 applies to ALL cars with it. E53/e65/e60/e63/e64/e66 | BMW LOGIC7
Edit: How old is that MAF?
