Another Head Scratcher

Scenario:

After star both gens online and balanced well. Turn on the rest of the necessary overhead switches.

3-5 mins after everything has been turned on left gen goes offline. It will not come back with the reset switch or flipping the Left gen switch.

What will bring it back online is turning off the cabin buss and turning it back on.

I have a 695A.

Any input would be appreciated.

Update finally found the culprit, a loose solder joint on the relays that connect to the lien contractor.

Intermittent electrical is truly difficult to diagnose. We kept at it as I want the plane right.
