Do you have any way of monitoring PID's? Have you checked for codes?
Very common issue. These are the more common culprits:
FICM - Might need to be replaced or repaired. Many options to choose from and a lot of it depends on how deep your pockets are. I went with Ed at ficmrepair.com for his premium repair. He's got a fantastic reputation around here.
Injector - could be bad or have stiction. A lot of guys have had positive results from running Rev-X or Archoil to help the stiction problem. I've run both and both worked for me. Eventually, though, you'll probably need to replace the injector(s). A contribution test is required to figure out which injectors need replacing.
Are you sure your fan kicks on? I've only heard mine once...it sounded like a jet flyby and ran for 5-10 seconds. I was hauling upwards of 10K lbs in the dead of summer through the Smokies.
