Unit cranks over a few times then it's dead. If I jump selenoid post, it will turn over again then it stops again. I replaced selenoid, same thing. It's as if there's a dead spot where nothing works. A quick jump across selenoid, then I can use start button. It cranks strong for about 3 sec then it's dead, nothing. A quick bump on selenoid, cranks fine for a few then dead again. Stator issue?
