I replaced the speed sensor and that did not correct the problem. Need to find a wiring diagram so I can search for an electrical issue.

What is it you are looking for.... easiest way to get one is to either buy it at autozone or canadian tire if you live in canada. or the public library.... search for haynes or chilton.

Where the spedometer cable goes into your transmission, that is where it's located.

What was replaced in the tune up? Usually the coil paks cause these types of issues. Also fuel filter or fuel pump will allow enough fuel to start and sputter like you describe.
