Does your engine have peak pressure sensors on the cylinders?  If so, a failing pressure sensor could cause this.  The press sensor can read lower than actual, causing more fuel to be injected to raise the pressure up, which results in higher exhaust temperature.  This is a common way a peak pressure sensor fails.

Check your MFI Duration Offset as well and see it it increased along with increasing exhaust temperature.
