SOURCE: wont stay lit
If the pilot flame does not touch the thermocouple, the heater will do exactly what you describe.
Get a short piece of copper tubing that will fit snugly over the thermocouple and bend the short piece so that it is in the pilot flame.

You should the value there should be a pilot ajustment screw
some times it is hidden under another screw but should be close to where the pilot light line hooks to the gas value

There are basically three things that can go wrong with the Warm Morning .
Sensor shut off. There is a sensor button on the back of the unit with a wire going from it to the thermocouple. This sensor turns the heater off if the flue is blocked, however it will also shut the heater off if the wire contacts are dirty, or if the sensor has gone bad.
You can test this by bypassing the sensor. Disconnect the two wires from the sensor and reconnect them directly together. If the pilot stays on, your problem is here. Try cleaning the wire contacts first.
Pilot orifice. If the pilot flame is small and doesnt look healthy, the pilot orifice may need cleaning. The hole is very small and can get dirty. Disconnect the silver tube and clean with electrical parts cleaner. Never try to clean the hole with an object like a pin, you may damage it. You may have to slide out the burner unit to get at the silver tube. (Always shut off gas before disconnecting lines and after you reassemble, spray joints with soapywater and look for small bubbles which may indicate a gas leak. Dont use parts cleaner around an open flame.)
Thermocouple can go bad but this is not as common as the first two problems.

The thermocouple may be worn out.
The thermocouple may have come loose from the valve.
The ODS pilot may be clogged with dust or lint and may need to be cleaned with air(less than 30psi)
The valve or regulator may be faulty.
