Cleaning the flame sensor was good but does the flame actually hit the sensor?The last burner to light is where the sensor is at and if the flames do not light all the way across and hit the sensor it will lock out. Could also be dropping out on pressure switch during the time it's lighting but you should get the code for that.You may need someone qualified to troubleshoot the problem. Guessing is not the way,Troubleshooting with a meter and the knowledge of sequence of operation is the way.
