Tach needle stops as outside temp increases

My tach works flawlessly until the outside temp reaches about 80 degrees and then the needle will rev to 5K but will not go beyond this point... when revs fall below this point the needle shows the correct RPM... Since it is heat related is it the needle within the dial face ( heat deflection/ warping ) or is it possibly electronics driving the needle? Ideas please and thanks.
