Furnace shuts down and will not restart...

Hello all! I am having problems with my gas forced air furnace... Model Number C9MPD100J14B1 Attachment 39995 (http://www.doityourself.com/forum/attachments/gas-oil-home-heating-furnaces/39995-furnace-shuts-down-will-not-restart-img_2499.jpg) Here is my problem... The furnace will start up and run for the whole cycle or just a minute or two... then shuts down and will not restart again until I open the front panel... turn it off... and go through the whole routine once again and now it has stopped even doing that...I am trying to solve the problem without the help of the furnace repair guy. I know it is not the thermostat as I have just replaced it with a NEST and pulled brand new thermostat wiring. Also, to confirm... when disconnected from the thermostat, it would do the same thing with the jumper cable (not sure if that is the correct term). The main gas valve is blinking a steady dim/bright sequence...
