I would suspect something fuel/electrical, but here is a slim chance 
answer.  I had the same thing happen to my VW GTI with a 1.8l solid 
lifter engine.  I had an aftermarket high lift camshaft.  On the way 
home from work one day while driving at a steady speed it just lost 
power.  After that even floored in neutral it would not rev past a 
certain RPM.  Don't remember the exact RPM, but it was somewhere around 
3000.  I limped home and the same thing the next day.  I was running 
programable EFI at the time and I sent it back to the manufacturer.  It 
tested out fine.  I checked everything still had the same problem.  
Finally I swapped the camshaft as it had a lifetime warrentee.  After 
that it revved like a banshee to 8000 rpm under full load like it used to.

Like I said a long shot.  I have never heard of this happening to anyone 
else, but I guess it is possible.
