Ice would seem to be a factor at FL400 much more than landing in Florida, unless you had some weird 1 in a million thing happen where an ice ball built up slowly and then melted all at once.
The idea that they just ran out would also imply the crew staring at fuel gauges headed toward the Big E didn't bother to mention it or land and buy more.
