I need a little central heating help, question?

[Jyruiz]

When I turn on the heater, after about 10 to 15 minutes, the heat goes off, but the fan stays on till we turn it off because then the house does not get warm enough to have the thermostat shut off the system.
Any idea what it could be?

Gas or electric heat?

Guess I should have gave that info as well, sorry. It is gas.

Standing pilot light or electronic ignition?

If the thermostat is not reaching temp, why does the heat shut off? Or is that your question?
Thats my question.
