Narrative:
On descent into ont, ca, the #1 generator dropped off line. Thinking it to be a simple tripped generator, I asked the captain if he wanted me to put the generator back on line. He acknowledged in the affirmative and I tried, but with no success. The captain then pointed out that the #1 engine was rolling back and had actually flamed out. At the time of the descent, we were xfeeding: xfeed open, #1 tank fuel pumps off with approximately 3200 pounds in #1 tank and 3600 pounds in the #2 tank. We went through the engine restart procedure with success and landed in ont with both engines operative with no far deviations. (Also, when we saw the engine roll back on descent, we started the APU and used it to power the remaining unpowered busses left by the #1 engine generator). (Also, the aircraft had been in maintenance for 4 days prior to this, the first flight out of maintenance. During maintenance, the main fuel tanks were drained.
