Loose cranks

Does that ring a bell to anyone ?

Basically we were riding in the snow this we, with lasco alloy cranks & we
discovered that after 2 hours the crank was loose on the axle. The day after, at
home, the crank was back at normal. Is there some kind of dilatation going on
with the lasco alloy ?
