No Brake lights on 98 K1500

Hello all,
I'm new to the forum, But Please help me anyway.

I have a 1998 K1500 Silverado, Today I noticed I have no rear brake lights, the 3rd brake light is working as is all the other lights, 4 ways turn, etc.. I removed the rear lens and tested at the plug and I have no power there or at the connector under the rear of the truck, I looked for the brake light switch but didn't see it (my 1990 was very visable)
Any Ideas....I'm electricly challenged BTW....
PLEASE Help.
Thanks,
Levi

I think it could be the stop fuse in the underhood fuse box
