This may not be directly related, but....... 2001 F250 7.3. 197,000 miles. For at least a year now, if I travel just above idle, (farm paths), for few hundred yards or so, take foot off of accelerator, the engine dies. Today, when I started it for it to warm up, after about three minutes, the engine died. Restarted fine, it did this twice. Any idea?
