Did you ever check the gate drive waveforms?  Just to rule out potential anomalies that could have degraded the MOSFETs over time. Thanks for the suggestion.  I believe I did check the waveforms when I first got things running, because the power draw was a little more than I was expecting.  Of course this is a while ago, so I don't remember details exactly.   At this point, I have a few parts on order from Digikey, so I can complete the build on 2 complete sets of boards.  This way I will have 2 complete running sets of boards to play with/compare. Once I have these boards running, I should have some time to review everything.
