Narrative:

ATC gave us a restr to cross bronc intersection at 11000 ft. We had been previously requested to go as fast as possible for following traffic. Tailwind was approximately 135 KTS, ground speed 625 KTS. Flight attendants were in cockpit reporting galley and cabin discrepancies. Captain (myself) was PF, and was looking up maintenance reporting codes for logbook, when ATC queried us about making bronc at 11000 ft, we were beyond any hope of making it (maybe 5 or so mi from bronc, approximately 20000 ft). On 2 pilot aircraft, if anything unusual is going on it is way too easy to allow autoflt system to let you miss restrs. With 2 pilots and more than 2 things going on, something is being deferred or unattended. Unfortunately once in awhile it is the operation of the aircraft that is unattended. After all, computers don't make mistakes, do they?

ON 2 PLT ACFT, IF ANYTHING UNUSUAL IS GOING ON IT IS WAY TOO EASY TO ALLOW AUTOFLT SYS TO LET YOU MISS RESTRS. WITH 2 PLTS AND MORE THAN 2 THINGS GOING ON, SOMETHING IS BEING DEFERRED OR UNATTENDED.
