97 Wrangler dies after its been running for several minutes,It will star after its cold again
Replaced the cam sensor because I scanned it after a check engine came on.
I was told that the crank sensor may have to be replace as well, But I don't want to keep guessing,can any body help me please.Thank you.

Try removing the Crankshaft Position Sensor, cleaning it with WD-40, and reinstalling it. I would definitely focus on this sensor.

Yes, I'd focus on the crank sensor, too.
Be advised: you may need to have the sensor "learned" by the ECM once removed and reinstalled.
You may also need a software update to be certain you have the latest calibrations for optimum operation.
