One possibility - insufficient gas flow or oxygen starvation might be making the pilot light dip when the main flame is on so the thermocouple bulb is no longer heated. This will cause the main flame to go out and restore full pressure/sufficient oxygen to the pilot.

It could be the thermostat sensor They usually have a carbon buildup. They are easy to install and not that expensive. Good luck

as with all water heaters they need flushed once in awhile to get rid of sediment in the bottom of the tank . knowing this from the get go most of us never seem to get around to doing it . even myself but I do have a unit that is supposed to prevent this by the dip tube that was built in has circular action in the bottom of the tank

iF YOU RAN OUT OF GAS, THE LINES MAY NEED TO BE PURGED OF AIR. dISCONNECT THE GAS FLEX AND TURN THE GAS ON TO PURGE THE AIR FROM THE LINE. dO THIS UNTIL YOU GET A STRONG SMELL OF GAS. aLSO, WHEN YOUR UNIT TRIES TO LIGHT, BUT THERE IS NO GAS, IT WILL TRY TO LIGHT THREE TIMES. aFTER THE THIRD ATTEMPT, THE UNIT LOCKS OUT. yOU MAY NEED TO RESET IT BY UNPLUGGING IT, OR IF IT IS HARD WIRED, JUST TURN THE BREAKER OFF FOR 10 SECOINDS AND THEN TURN BACK ON. tHIS WILL RESET THE GAS VALCE TO RELIGHT. gOOD LUCK!

Error code EA - No sparks for the electrodes
The ionization electrodes are not making sparks when water is flowing. There are many reasons for this problem and here are some; low gas pressure, fan speed is low, wire connections are loose, the air in the gas line, no gas.
