In most fighters, that is true... But then they are not meant to fly that fast for that long anyway. Mach 2 flight is used in combat, for escape or rapid closure to the target. The F-22 is able to fly supersonic without the use of afterburners, so it can maintain Mach 1.2 for over an hour without any problems.
The SR-71 of course can do it for 90 minutes because the engines were designed to do that.
