Hi folks, Posting this for my dad, he doesn't internet. He has an 05 king ranch he uses for towing hay and equipment. It's been studded and chipped, not sure what else. He uses a tow tune when towing. He said today it just died on him while he was driving. He said he could barely get it started on ether. Ran it down the road a few miles, died again. Got it started again on ether and to a local shop he takes his truck to. They scanned it for codes, no codes. He said they changed the fuel filters and drained the tank completely. Fresh fuel, still doing it. Will run a few miles and die. Anyone have any ideas? Thanks for the help. My dad's a pretty competent mechanic so if I can point him in the riggr direction he'll suss it out.
