I had a similar GPS intermittent issue that nearly drove me crazy three years ago. It turned out to be an intermittent grounding path for the antenna that was causing a position failure once every two or three days. Fixed it with a little grinding and placing sharp shake proof washers under the antenna ground terminal.
