Question about Desa International Blower Glow Warm Wall Heater
This sounds like a problem with your thermocouple.
Just remove the end of the thermocouple from where is goes into the gas valve and leave the end that goes into the flame in place.
Clean the end of the thermocouple connect by scraping off just a little metal from the end just about there the nut tightens the thermocouple into the gas valve. After you have exposed some new metal do the same inside the valve where the thermocouple seats into the gas valve.
Use a small pic or similar item to scrape inside the gas valve to expose some new metal there also.
Now reassemble the thermocouple into the gas valve and see if the heater works.
Here is a link with some more instructions.

Clean or change out the pilot assembly. Check for a lose connection of the flame rod at both the pilot assembly as well as the gas valve.

You may test by placing a multimeter on the red and white leads coming to the gas valve. you do not need to disconnect the leads first but you can

The power pile (pilot generator) is defective. It produces a milivolt signal to ensure to keep the gas valve open. If it goes bad, the valve thinks the pilot is out, even when you are holding the button down, so when you release the button, it shuts the gas off to prevent excess gas buildup and a possible explosion.
