When the problem occurs, are you saying it cranks good but won't Start? Or, it won't even crank?

In the diagram, check the fuses for voltage, use a voltage tester. The two at upper right, both should be hot with key in the crank position, actually one is hot in start or run. The fuse at lower left is hot all the time. Voltage to the load switch side of starter relay is hot all the time. Voltage to the coil side of relay goes hot with the key in the crank position and is wired through the neutral switch. Another possible issue is your security system, I can't be sure about that?
