Sputter when a\c off?

So I am relatively new to diesel engines! I have a f250 6.0L, that every now and again sputters and idles rough, when the a\c is off? Yes I did say off. It's only done this twice, but when I turn the a\c on it goes away and runs fantastic. Not sure what could cause this, and think it's a little weird that it's not consistent. Sometimes I run it without a\c and it's fine, but this has happened twice now, so I thought it might be worth figuring out. Any help would be greatly appreciated, thanks!

Sounds like the A/C clutch may be going out. When mine died, made the truck run rough and at one point, not start.... That day, the clutch finally locked up and smoked.

Thanks for the response, I will definitely have to look into that. Sometimes the truck does seem to take a bit to turnover. Could very well be the issue.
