Request timout is only for ping time, if the relay has denied the request. After X attempts (default 4 iirc) your router will stop asking and be on it's merry way to the next hop. Some ISP's don't allow their relays to be pinged....You'll be waiting until it hits the default number of max hops because the destination doesn't accept pings. I'm assuming that the OP let it go 2 or 3 more hops after that failure before giving up.
you can change to fewer hops if you want, just means you may not reach the destination....but the tracert needs to complete...
