Perhaps the cursor keys have been put into application mode and your
terminal type isn't supporting them in that mode?

When things are working, if you run:
  print -n '\e[?1h'
do they stop working?

If you run "bindkey", you'll see two batches for the two sets of cursor
keys; for me:
"^[OA" up-line-or-history
"^[OB" down-line-or-history
"^[OC" forward-char
"^[OD" backward-char
[...]
"^[[A" up-line-or-history
"^[[B" down-line-or-history
"^[[C" forward-char
"^[[D" backward-char

If those two sets ^[O<foo> and ^[[<foo> differ then this might explain
it.  So, (1) bind both sets the same and (2) see if "stty sane" helps.
And:  print -n '\e[?1l'
