Could my RPM sensor kill my ign while driving

[kevin at baisley.net]

 89 200  This problem has happened to me 3 times while driving my car in the last 8 weeks. Driving at normal speeds the car will just die. I pull over to the side of the road and no spark. I crank the car and pull the codes and get 4444 no problems. Let the car cool of for 15 to 30 min and it starts up and purrs. It is not the ign switch and I spec out the coil and it measures out ok. The only thing I can think of is the RPM sensor down on the flywheel. Am I correct in my thinking that if the car dies while running the crank postion sensor would not kill the car? I have ohmed out both sensors and there is continuity. I do not have the spec so i just measured it out. I removed and inspected sensors and they look good.

I have ordered a new coil just in case 

Any thought would be greatly appreciated !!!

TIA
