Heater shuts off including the pilot light after reaching hot (~1 hour or so)

My 8+ years State Select water heater recently shuts off including the pilot light after reaching hot (~1 hour or so). Note that the heater won't be lighting up using the pilot ignition but it works if I use external source (i.e. matchstick).

I've checked this forum and the internet and it seems I have to clean up the flame sensor or replace the thermocouple or the gas valve. I tried cleaning up (not thoroughly) and it doesn't help so before I take it all apart and try in that order, I'd like to ask if anyone's heater had the same symptom as mine (i.e. shut off after a short time)?

I would try the thermocoupler. It's easy enough to do & doesn't cost a lot.

Need the actuall series # and model #. ( Serial #?)

If you have a corderite diskmodel it may be clogged with lint. This causes the unit to starve for air and overheat. This in turn trips the thermal safety switch which shuts off the gas. Only when the burner chamber cools you can relight the unit.

There are a few threads on this issue and how to correct.
