tl;dr Shortly after takeoff electrical fault interrupts throttle position signal, and the "safety" logic causes the engine thrust level to be reset to idle. The engines restart automatically once the data link recovers, and this took place, but not soon enough to sustain flight. The cause of the short was water ingress into a DC electrical panel, pulling down the bus voltage enough to cause faulty frames in the throttle position signal.
