Deg C          Ohm
 20           1000
 40            500
 60            250
 90            100
120             50

Changed any components lately?  4000 rpm is the point, on a 5-cylinder
engine, when the 'sparks per minute' rate reaches the limit for a
4-cylinder engine.  I'd also check the coil grounds and the primary
resistance.
