Your electric power steering system is detecting a fault and shutting its power assist off for your safety. It could be many things -- faulty sensor or electrical short or loose connector or ...

It is hard to diagnose a problem that comes and goes. Wait until it happens regularly and take it to a mechanic. If I recall correctly there are some EPS checks in the service manual you could try on your own (like resetting the straight-ahead position).

Easily. Or just a slightly corroded connector.

Check the harness on the rack and maybe spray conducting grease on them.
