I HAVE A 82 280ZX TURBO. IT WILL JUMP AND RUN ROUGH THEN QUIT 5 MINUTES LATER, THEN IT IS DEAD. I THINK THE BATTERY HAS A FULL CHARGE TO. IT HAS A NEW STARTER, ALTERNATER, WHAT COULD IT BE. IT RAN PERFECT UP TO THIS POINT. IT DID BLOW OUT A FUSEABLE LINK WHEN I PUT IN THE NEW ALTERNATER, BUT THE GROUNDS SEEM GOOD, AND THE LINKS STILL BLOW? HELP ME PLEASE
