I have the same camera too, love the pics from it, but my 240v PS is dying when overheated and the camera turns off - I think that is what is causing it. I tried a second C-750 and that does the same thing. So the only common item was the plug in power supply (not the Olympus model, hmmm). Need 5.5vdc at 1amp minimum, so might be looking for a bigger power pack.
