Ignition coil reisitance

[fishboy7504]

I am working on a 1991 Johnson Faststrike. I have been having trouble with the motor running when it's hot, it runs like a charm when cold. I checked the resistance on the ignition coils, P# 0583740. I am reading a @600 resistance between the spark plug terminals on 2 seperate coils. The other one I'm reading infinity, which is what I would figure since it is two different circuits(cylinders) on each coil. Does anyone have any thoughts on this and could this be a reason for my trouble? Thanks and tightlines.
