Try replacing the batteries in the key. Does the remote central locking work o.k. The switches themselves do fail and you must replace them. The only other item that can be faulty is the immobilizer ring wich reads the key signal and sends it to the switch. I would clean the key lens and replace the batteries. If problem still exists replace the immobilizer ring. These type of problems can be expensive to diagnose.

Gs 300 ignition switch

Best guess is the Solinoid (on top of the Starter) is the cause.
There will be a Main cable from the battery bolted onto the Solinoid. Near this (a separate terminal) will be a much thinner wire. This supplies the current from the ign. Sw. to the Solinoid.
Disconnect it. Re-Connect the battery.
If this doesn't fix the problem, Repair the Starter Motor.
If this fixes the problem, turn the Ign. Sw. on and touch the wire back to the terminal.
If the problem is back, the problem is the Ign. Sw.

When i turn key off it continues to try and start and eventually runs battery down

Jeffs solution (above) is for a different problem. If the Starter Motor continues to turn with the Ign. Sw. off, yours won't be a Starter Motor problem. However, the most likely cause is either the wire to the Starter Solinoid or the Solinoid itself.

I can't see the alternator being the cause either, as suggested above.
Try this
Disconnect the thin wire from the Solinoid (this is the one that activates the Starter when you turn the key).
With the battery charged, the Starter shouldn't work. Put the wire back and try again. If the same problem is there, quickly remove the wire.
One of 2 things will happen:-
1: The Starter will stop. The cause is in the wire to the Ign. Sw. or the Ign. Sw.
2: The Starter will continue turning. Repair or replace the Solinoid.

Ignition switch

sounds like the ignition switch isn't 'resetting' correctly. You'll likely need the dealer to fix the issue. Or you can try replacing the ignition cylinder, but usually requires special tools as it's 'secured' to prevent auto theft.

Remove plastic covers surrounding ignition sw.

How to change ignition switch on a 92 4w drive k1500 series truck, manual transmission

When you say ign sw,do you mean the key and tumbler or the ign sw under the dash?
the key and tumbler needs the steering wheel removed then you will clearly see a small screw remove it and the switch slides out.
Now if under,remove the knee bolster and you will see the switch on the side of the steering column tahe the two wire harness out remove the two screws and reverse for install.

Check gear selector neutral switch is ok,
