92 Lesabre anti-theft relay

[ga_pechs]

Help!!! car runs good but shuts off after 30 minutes or so....will crank back up after it has cooled down (30 minutes to an hour later).....have replaced the oxygen sensor & camshaft sensor. Now we have bought an anti-theft relay but have no idea where it is located. Can anyone please help with this or for that fact any other suggestions???????

It sounds like you need to install a crank sensor, not the starter enable relay, sometimes called "anti-theft relay". If the relay was bad, it would not start in the first place. If I understand your post correctly, the car starts, runs and then shuts off, and starts up after cooling down, all symptoms of crank sensor failure.
