Mine started doing this after a winter of sitting outside and not being used - I think that things had just stiffened up a bit with age. (Happens to the best of us). I worked it up and down a few times, making sure that the hood was folding OK and helping it manually at the stopping point. Eventually there was a bit of a clunk and it went past the stopping point and has worked fine ever since. I'm going to get back in there and lubricate the pivot points, but in my case, it just needed some use to get moving again. Worth noting that I'd also cleaned, redyed, and reproofed the hood, which might have caused the fabric to stiffen slightly in place until it's used a few times.
