Ok, I tried my best to clean the vent coming from the outside into the house that connects to stove. I removed the combustion blower and cleaned good, put on a new gasket and vacuumed out a good portion of hopper. I also removed the vacuum hose and blew a can of air into it and put back on. I started the stove back up and it took prolly 3-4 times to get the pellets to feed. It went for 15 minutes and shut down again. I also believe I smelled smoke coming from the venting coming out of the stove that goes out the wall. Hope I didn't mess one of the pipes cleaning it. I worked on it since I got home from work at 4 and seems like I got no where with what I did. I'm frustrated and feel like I'm gonna have to spend money to get someone to come clean and inspect it.
