Cozy Wall Furnace Pilot Won't Stay Lit

Have an older model Cozy furnace. Pilot would not stay lit, so I replaced thermocouple. After replacing, furnace worked great for a few days, the shut down. I got the pilot lit and it worked for a few hours then shut down. Was able to get pilot lit again, this time it only worked for about an hour before shutting down. Now I cant get the pilot lit at all, even if holding pilot button for over 3 minutes. Any thoughts? Thank you!

    Maybe check the incoming gas pressure. Natural gas is usually 6-12" inlet propane is 12-14" inlet. Remove and clean pilot assembly and tubing. Dirt rust and spider in them are common. If you have gas pressure at the valve inlet and can't light the pilot either the valve is bad or something is plugged up.
