LS3 power issue

have a 66 vette restomod with a LS3 engine. Have 1400 miles on the build with no issues, Today stopped at a stop sign and the brake light came on and could not accelerate at all, car stayed on idle. shut the engine down and restarted 5 times and got power back. brake light stayed on, drove home, stopped hard and same thing happened, car remained on idle. any help would break appreciated
thanks

Is your TB drive by wire or cable driven?
