We just had a bad batch of pellets from our supplier here that caused very similar issues.
Recently, I have come across a lot of cases where pellet stoves shut down prematurely after 3 to 6 hours or right after the start cycle when the fire lights up. Most of these intermittent problems are due to aging parts in the automatic exhaust blower vacuum sensing safety shutdown. This safety system employs a hose and a vacuum switch. The vacuum hose is connected from the exhaust plenum to the negative port on the vacuum switch. Most pellet stoves use the negative port because the hose barb on the exhaust plenum is sucking air in and pulling the vacuum switch closed. The positive port is where air blows into the vacuum switch and this positive pressure closes the switch. Therefore, if the exhaust blower shuts down or dies the wires connected to the switch cause an open circuit and stop the auger from turning which in turn shuts the stove down.
In the case of Englander stoves with dual augers, the switch is only connected to the top auger which also stops the pellets from feeding and shuts the stove down. Usually, this system indicates a bad combustion (exhaust blower) or venting plugged with ash or a dirty stove. It also can indicate a bad door gasket or a bad ash pan gasket if there is one on the stove. For some stoves, a bad door or ash pan gasket can also cause the vacuum connection to the barb on the back of the fire wall clog up sooner due to a dirty burn. A vacuum error can occur if an upgraded high speed blower is installed in a Magnum BabyCountryside stove. To resolve this issue, the damper needs to be adjusted in the air intake on back of the stove. I have also seen the vacuum switch with the hose on the wrong port or the wires not connected to the correct connectors. However, this would cause immediate failure.

Aging vacuum hoses get stiff, brittle and crack, and some get stretched where they connect to the hose barb. The bladder type membrane in the vacuum switch also gets weak and may develop a small tear or leak. Pinpointing these failures can be challenging because the above issues may not show up until the stove heats up. The hose and bladder membrane are connected to either metal or plastic. The heat expansion differs for those two materials which causes a leak and the part fails. Therefore, the auger stops feeding pellets and the stove shuts down. Some stove manufacturers may have changed the formulations of their switches and hoses to save money.
