Why does Find my iPhone keep logging me out?

Whenever I click on the Find my iPhone app it asks me to log in even though I never logged out.

It's for security.

A lot of web sites and apps log you out automatically after 10 mins - half an hour.
(Or as soon as you exit the app, even if it's sooner than that.)

Staying logged in forever is actually the unusual case.

If I try to take a picture it tells me I don't have enough storage to take a picture.
