Narrative:

Numerous delays out of phx and las; we left for jfk over 3 hours late. Starting the descent; fatigue was apparent. We were instructed to cross harty intersection at FL230. ATC started VNAV descent from FL370. FMC was properly configured and aircraft was on flight path. Descent progress was checked and normal. Both pilots got distraction momentarily by ATC clearance and at the same time the aircraft left VNAV path and slowed to 250 KTS. ATC inquired if the crossing restr was going to be met; at same moment the flight crew realized what was happening. Aircraft was 5000 ft high and we were reclred to cross stw at FL230. This last restr was met. There was no conflict with any other aircraft and ATC did not make any other inquiries.
