i have yet to see one, i don't belive any chevy car came with a 3.8L and was a stick shift. tho i do know for a fact that the camaro v6 3.8L comes with a 5 speed manual but that car is rwd...so maybe you can look into that and search up some threads that maybe have done what you are trying to do...
okay its hard to tell what your problem is with out me seeing it and seeing how the car acts while its one for those 15 seconds or how it dies but with sitiuations like these its sounds like one of 3 main issues
one, have auto zone check your altinator...it might be running out of juice, or you...
