I have a 2001 426 just bought it last week. I took it for a ride on wednesday for a couple of hrs and it ran excellent. The next time I took it out I was letting it warm up and it only ran for a couple of minutes and then would die. Couldn't get it running again. I got home picked up a new plug and it did the same thing ran for about 2 mins the would die. Wouldn' t start for awhile. I got out my manual and just started to go through the electrical checks and everything was good until I got to my ignition coil. My primary mesaured in spec but my secondary is supposed to be between 9.5kohms to 14.3 kohms. I was measuring approx 22k. Could this be causing my coil to heat up and open up when it gets hot after running for a couple of minutes. Any help would be greatly appreciated.
