1) Could be the vapor sensor. That's a suspect.
2) General troubleshoot: clean burner and combustion parts, clean air intake, bleed air from gas line, check gas pressure. Color of gas flame should be clear blue, and flame should be strong, and no combustion by-product dripping back into combustion chamber. No chemicals of any kind stored in air supply. Plenty of fresh air. Water heater in hot attic needs more air. If water heater has igniter, then igniter has to be checked. Flame sensor must be positioned correctly and operational at time of combustion, or sensor will signal gas control to turn off gas. Gas control valve can be bad.
