Lots of good ideas on what to look for so far - and it could be any of them. But I would also be sure to evaluate the tightness of the tuning pins on the offending strings. I have had tuning pins that were loose jump or "BANG" spontaneously and go way flat. I have usually seen that occur in the bass, not so much in the treble - but hey, why not the treble! Put you tuning lever on those pins and take just your pinky and give the tuning lever a nudge and see if the pin jumps with a good "BANG". And check all the other suggestions also.
