Medium large transport cleared to cross hayed intersection at FL190. Descent begun in vertical speed then changed to VNAV. Somehow, VNAV was not engaged or became disengaged and aircraft approached hayed at FL240. ATC gave flight a 360 degree turn in order to make the altitude crossing restr.

Narrative:
On the williamsport 1 arrival (fqm.FQM1), cleared to cross hayed intersection at FL190. It was set up in the FMC. Descent was initiated in vertical speed, then VNAV was selected. I was distracted by a call from a flight attendant in the cabin and did not catch the VNAV not engaged. ZNY called about 5 NM before hayed and asked if we were going to make the crossing restr. We then received vectors for a 360 degree turn to descend. There appeared to be no traffic conflict. Contributing factor was that first officer was off frequency talking to company and getting ATIS.
