Tps falling out

I have a 30008 meanstreet on a roller 454. It was running great until recently. I was accelerating and the car just shutdown for a second, almost like it lost all fuel or spark, then it would all of a sudden come back to life. After recording a data log I found that the TPS sensor was dropping to 0 volts. I did a sweep test and found random dead spots that would come and go. I installed a new sensor and still have same issue. I haven't found any poor connections yet.
