Ok, so I got a box of these a couple months ago, and at first I loved them. I hadn't smoked any in a few months until last weekend. It had bad burn problems, flavor wise I was happy, but had to keep touching it up, and about 2/3 of the way in I set it down and moved to yard work. I had another one today, and had the same problems. Is there something I should be looking at. I have them in my cooler with 65%...any thoughts.
