Check the eye terminal connections at the starter motor. Check for corrosion or looseness.

What you are searching for is a voltage drop, which draws current. Basic electricity. I am trying to help you seek out on which side of the system the problem is.

A loose battery terminal will do the same thing. Oh, and I don't care if it starts "just fine" this has absolutely nothing to do with it.

Need I find the specs for the coil, the ignition circuit and the alternator and ohm test them. I would check them all cold and right down your findings then run it for awhile to get it hot stop and test all components again and see if one of them is reading a lot more ohms then cold test. Also check wires from starter to relay or the breaker. This is the kind of issue that drives us all nuts.
