Marshall,

The last time I had a system with random lockups like yours I eventually
traced the cause to an old power supply. Those baby beer can
electrolytic capacitors eventually dry up and don't filter the AC ripple
voltage the way they did when new. The lockups vanished as soon as I
replaced the P/S. Do you have a spare you can try?
