Run for 5 min then shuts down ????

If any one can lead me in the right direction. I have a H150 pool heater, If it sits over night the first time I fire it up it will run for about 5min then shut down. I reset it then it will run for 2min and each time I reset it it will run shorter and shorter. unless I wait several hours then it will once again run 5min and so on. I did notice when it is about to shut down I here it trying to spark the piolt even though there is good flame, heat exchanger in not blocked was cleaned out. Have plenty or gas and water flow.
Thanks rob

It sounds like the thermocoupler may be going bad, or the temperature sensor is going out. It may be something to look at.
