Check the fuses first. B8, C1, C2, C3. If they are good then either the ECU isn't getting the w lead signal or the relay is broken.
To check the relay, it is number 7 in the rear relay carrier, jumper the 2 larger wires coming in, then try starting the car. If the car cranks, but no start it is the CLU not sending the w lead signal, or the ECU is broken.
If it starts, replace the relay. if there is still an issue, it is the clutch switch wiring.
With a broken CLU or ECU - time to start digging deep in the pockets.

Checked all the fuses under the dash, everything was good and snug with no blown fuses. I changed the cruise control switch on the clutch while I was down there as well.
Checked relay number 7, it had a small amount of corrosion on it so I cleaned it with alcohol. It has started easily since then, but since the issue is so intermittent I can't be sure that mended it.
