Well - the "only happens when it's warmed up" sounds odd but the rest sounds like classic master cylinder failure. I used to get a sporadic brake pedal in the race car until I realized that the front hub nuts were coming loose - you may want to resecure your hubs and all the brake hardware first and see if it's something that was overlooked before spending the $$ for a new master cyliner.
