FE, valid point, but there have been a number of incidents where one or more engines flame out and the crew starts troubleshooting the electrical system without realizing the engine(s) quit.
We had one incident on a 767 where both engines quit during descent (ice crystal icing), then re-lit a minute or so later. Pilot squawk was 'temporary loss of electrical power' - we didn't know the engines had quit until we looked at the FDR.
