"Engine Disabled" message..........

We have had the Engine Disabled message come 3 or 4 times in as many days and have to go thru the bloody recal setup again and again ,its the wifes car and she is mighty pi55ed off with it at the moment ,it has done it before but not as many times as this, my question is is something really on its way out now ? It is a P38 2.5 dse 1996.

Thanks .

Changed to second remote keyfob and all seems to be well .
