What is litre size of your engine? The 3.1 showed a theft system? Anyway, the purple wire at the starter solenoid should be hot with the key in the crank position. You'll have to test when it refuses to crank. Yeah, intermittent problems are a pain. When the problem occurs can you tell if there is a load on the starter circuit? Watch the lites, if they go out or dim, there is a load on the circuit. If not, open circuit somewhere. I guess you tried cranking in neutral?
