The closest thing to this problem I have encountered with a TBI motor was the pressure regulator in the TBI..poor quality gas and water had rusted the spring into two pieces,, the thing would run fine some times, then spit and sputter, not go over 45 and just quit once in awhile..I replace the regulator and that fixed it......Hope that helps,,,some of these things can be a nightmare...
