If your pool heater is outdoors in a high wind area, the wind might be blowing it out. In some cases you can solve this by installing an outdoor vent cap to extend the distance from the end of the exhaust and the combustion chamber.
Answer:
try changing the "thermocoupler"( not sure of the spelling) The piolit light heats the thermocoupler. looks like a little metal rod that sits above or right next to the piolit light. when the thermocoupler is heated it produces a millivolt of electricity the power it produces is what keeps the gas vaulve open. this is a safety feature, if the piolit light goes out the gas will shut off so that the house does not fill with gas. This is why when you light the piolit you must manually hold the button in until the thermocoupler heats up. Gas appliances should only be worked on by licienced pros, don't risk the lives in your house in order to save a few bucks.

Check to see if you pilot light is lit
Most likely your pilot light is out
The pilot light on the stove may keep going out due to a dirty or clogged pilot light assembly, a faulty thermocouple, or a lack of gas flow. It is important to clean the pilot light assembly and ensure proper gas flow to prevent the pilot light from going out.
A pilot light can go out due to lack of fuel, a draft blowing it out, or a malfunction in the ignition system. Common reasons for this occurrence include a dirty or damaged pilot light assembly, a faulty thermocouple, or a problem with the gas supply.
To turn on the pilot light on a gas appliance, locate the pilot light button or knob and turn it to the "pilot" position. Then, press and hold the button while using a long lighter to ignite the pilot light. Keep holding the button for about 30 seconds to allow the pilot light to stay lit. If the pilot light goes out, repeat the process.
Problem with plug shorting?
The pilot light may keep going out due to a dirty or faulty thermocouple, a draft in the area, insufficient gas flow, or a problem with the gas supply.
The water heater pilot light may keep going out due to issues with the thermocouple, a draft in the area, or a problem with the gas supply.
There could be a draft causing the pilot light to go out.
It depends on which way the wind is blowing. Because if the wind is blowing into the side of the plane then the pilot has to fight against the wind just to keep the plane on course.
The pilot light on a furnace may keep going out due to issues with the thermocouple, a dirty or clogged pilot light orifice, a faulty gas valve, or insufficient gas flow. Regular maintenance and cleaning can help prevent this issue.
Are both your brake lights blowing out? If it affects only one light: it could be a bad light socket, or a pinched or frayed wire that is shorting out.
