Default LS3 416 Tach quit working now surging????

TS 416 LS3 stroker was running fine and then all of sudden the the tach stopped working and it started surging and down on power. Changed out the crank sensor and that didn't fix the problem. Could this computer be bad or a ground wire maybe loose?
