Hi Thermo, welcome to FTE!
Unfortunately things sometimes go wrong with engines as complex as these are, but for the most part they do pretty well. With as much engine warranty as there is left I wouldn't hesitate to buy it once the problem is corrected. Scott is probably correct in that it's likely a sensor problem.
Take a look around and also make sure to visit the TECH FOLDER found at the top of the 6.4L forum. Lots of great info to be found there that would be beneficial for you to know before you make the purchase.
Let us know if you get the truck, and be sure to post pics!

Talked to service dept today and they said 1 of the engine thermostats failed not sure which one I know there are two. And from what I have read they take 3 hrs book time. Could not pick up truck today.will tomorrow arranged to drive truck for a couple days before buying so I could check over and make sure no other problems.

Actually there are two fully independent cooling systems on the 6.4. There is a separate system with a separate pump and radiator for the fuel cooler and variable turbo actuator.
