I assume you get the pilot lit ok but it goes out and so does the stove?
It may be a dirty or defective Thermocouple. I know you said it was cleaned but it may be worth a shot to focus on the thermocouple. You can try this...
1. With the Pilot out, take a stiff tooth brush and clean the thermocouple (sides and tip). This is the item that looks like a round metal stud (not the spark tip) to the right on the pilot assembly as you look at the assembly from the front.
2. after cleaning, Light the pilot. It should have about a 1 inch flame that either touches or comes very, very close to the thermocouple. (The thermocouple is a safety device that senses a constant flame from the pilot and, in some designs, powers the O2 depletion safety assembly. Working right, if the pilot goes out, it causes the gas to shut off. When defective, it falsely thinks the pilot is out.
Give it a try. I have to clean mine every year before winter or it does the same thing.
The Thermocouple takes a ton of abuse and they can go bad. If you have tried the above suggestion and it does not work, you may want to get another thermocouple and, if you are qualified, replace it or have it replaced. After tons of research, I found a parts reference list at:
www.worldmkting.com/support/documents/GasParts-Misc.xls
Look at line 110 for parts listings for this model.
I then did a search for the called out thermocouple and found them at:
empireheaterparts.com
ND0803-8 Thermocouple 1x $14.95 each.
Hope this helps, if not, it could be a defective O2 depletion sensor (ODS) the same web site has these as well.

Good luck! -Dan
