Flameout and wild temperature swings

[Samm-Smoker]

I have a pit boss 820, which I've had for over a year. I've been trying everything that has been suggested and nothing seem to help. I frequently have flame outs and the temperature swings + 50 degrees above and -20 below whatever the temperature I've set. Yesterday this almost ruined $70 or ribs. I'm having to constantly monitor. Fortunately I caught the flameout, took everything out so I could remove the mountain of pellets in the box. Had I not done that, once the pellets ignited they would have roasted the ribs to a crisp.

I've been very patient with these issues, but I'm about to dump this POS and get a Traeger.

Any last words?

is your fan ok?
if the fan is running a little slow the fire will not be as hot and your auger will try to feed more fuel to help heat up,
then it cannot burn the fuel/pellets efficiently and will flame out.
I don't know if that is your problem but it's worth checking out.
