Sounds like dirty flame sensor or dirty burners

Try cleaning your flame sensorwith steel wool/fine emery cloth. It's a single steel metal rod located in front of the burners with one wire going to it. Hope this helps. If it doesn't, call for service. You may have a bad board, gas valve, limit, etc.
