Canon G1X loses focus periodically in video function

Dear all, I'm trying to figure out what's happening here; I was videoing a refinery fire in Richmond, CA today and wanted a long clip; I set the camera on steady object, set the zoom to 16X, and began to video. Every two minutes or so, the picture lost focus, became completely blurred, then reestablished focus. Do any of you have an explanation and a solution for this?
Hopefully,
Mack
