Hi
\015\012Sounds like you have 2 problems here.?

\015\012The engine stuttering sounds more likely to be an air leak on your brake servo system, weakening the mixture, and this will give you a lumpy tick over.

\015\012As for the stop lights, No 1 check its not the fuse.
\015\012You need to confirm you are getting a live feed to the brake switch with a 12v test light.
\015\012If OK, bridge this connection and recheck your feeds at the stop light bulbs.

\015\012Good Luck
