Does it work for any host/service? Did you perform your testing of your
script as the nagios user? I presume that nagios was restarted or
reloaded after modifying the timeout above.

No, the output information from a host check is not down-populated to
all its services. The check really is timing out.

I would log entry and exit times from your script to see if it really is
taking >90 seconds to run as well as log important milestones within the
script (fping start, fping output, fping end, snmpwalk start, output and
end, etc). I would also verify that it runs as expected by running the
command definition exactly as specified as the nagios user.
