Check engine light

CEL came back on. I scanned it and said truck was running lean. I cleared the code and all was fine..it was after I towed my snowmobile that it happened. That was 3 weeks ago. Now after this past weekend the CEL came back on and running lean again. After I towed my snowmobile roughly around 400 miles. Truck has 16k moles on it. Has this happened to anyone else

What was the code? Unless you're running real dirty fuel, I can't see the filter is plugged enough to starve it of diesel at 16k. I've not seen a diesel run lean and not show running problems, like not running at all. But this 3.0 is all new to me, as far as diesels go.

Haven't seen that after towing my sled.

Isn't it under warranty? Have the dealer look at it and get a detailed report as to what happened.
