Does this describe what you are seeing?
If do not have a multimeter, get one... the $20 one linked above is a killer deal! With that you can monitor voltages in the set as the problem occurs.
If the set has a tube B+ rectifier like a 5U4, you might observe it as the problem occurs perhaps the filaments go dark or the plates turn cherry red or the whole tube glows purple. Might be a clue there!

That seems to be exactly what is happening to my set. So..where do you suggest i go from here?
