All dash lights lit up randomly on highway today

[Flybynight]

First with cruise set, going up hill, just as it dropped down a gear all light flashing, but still running, clicked off cruise, cruise flashed a couple times and then all out.

Left cruise off

Happened again, no cruise, climbing hill on highway, all dash lights flashed, possible delay in power, then back to normal.

Anyone know whats up? Its going in for a bunch of work soon and if I can nail this down I'll have it fixed too.
