Mend Saunier Duval Thema F23E Hot Stay Gas

Saunier duval Thema F23E. Hot water does not stay constant?

My boiler gas comes on when the water is turned on but goes off after about 30 seconds. The hot water pipes in the boiler get hot but the hot water at the taps goes hot and then cold again very quickly. The gauge shows 60 degrees but the tap water never reaches that temperature.
