I woulld look at the EGT temp to see if it changed--if not I woul= d pull the engine data management system for a possible error--this happene= d to me with a fuel pressure problem--fuel pressure went to zero--fuel flow= was fine and there was no change in EGT or CHT--any change in CHT should c= ause a change in EGT.
