Tried lighting my Sante Fe and having trouble with it. I cleaned the hopper and auger out. I have the feed gate all the way open. When it starts it will run pellets in the fire pot but doesn't seem to put enough in the pot. After the fire starts it will start to put pellets in the fire pot but by that time the fire is about out and will eventfully go out about a minute later. After the fire goes out if you reset the stove it go ahead and take off just fine. Haven't ever had any problems. Any suggestions
