avipak strobes not firing during flight

Just did my first night flight after completing phase 1.

I have an Avipak box firing wing and tail strobes. If it's just on battery power on the ground, all strobes work fine.

Once flying, the strobes stopped firing. If I switched them off and on, I could see the wing tips flashing for one or two sequences, then nothing.

When I returned to ground and shut down engine, the strobes were working fine again.

My guess is it's somehow connected to alternator output, which would increase at cruise power. However, no issues with any other electronics.
