Failed Engine Sync - Error code

[acamp32962@bellsouth.net]

I have a 300 ETEC with only 35 hours. I was 20 miles offshore and the engine died. Error code read "Engine Sync Failure, See Dealer" i barely limped home in SAFE mode. Does anyone out there have any idea what that error code means.
Dealer simply put me in a long waiting line so i have no help from him at this time
