Dodge B300 440 start problem

Ok 1978 440 Dodge B300
There has been no issues and it has been running well.
Today though I turned over the key cranking the engine.
The engine continues cranking and will not fire until the moment I release the key.
Once the key gets released it fires up and runs well.
What may be the troubles here I wonder?

Ideas?
Thanks!

    Have you done anything with the ignition system lately? If I remember correctly, as you crank the eng you bypass the ign resistor - something like that - and it applies full voltage to the coil. I'm thinking that wire is open or the ign switch is bad.
    I would check for voltage at the coil when cranking.
