My friend picked up a brand new f350 ps on Thursday. Left from Minnesota to Arizona Saturday. About 900 miles into the trip, while passing, he got a "reduced power" message and the truck slowed to a stop, killed and will not restart. He is now stranded at a Ford dealer at Dalhart, TX while he waits for them to open Mon morning. Anything he could check himself while he waits? The truck cranks but will not fire.
