Is it possible that the board has a “crown” or arch that you have facing down? (Like a bowl sitting on a table) If so, it is easy to get it started on one side where it never will get to the other side where the crown (arch) runs up already. If you can find a piece of wood that is already pretty flat, try running that over the jointer a time or two to see if it continues to miss the last half or if it cuts all the way across.
I have had this problem with a badly crowned board. The only thing to do was to cut it in half and use it for smaller pieces in another project. Then, it worked fine. The best thing is to reduce the board to near the needed length and then joint it with the crown facing up (bowl upside down on a table) so you can take material off of both ends, perhaps reversing the board between cuts until it establishes a long enough straight edge to register on the outfeed table.
