Well, I'm going to take a guess that your car is newer than 1988 and if it is then I'd say it has to do with the immobilizer and that your security system is cutting fuel to the engine. try and bypass the immobilizer. First, you need to figure out your immobilizer bypass number(should be in your handbook or in servicing records) then follow this video sounds kinda weird but it might work? https://www.youtube.com/watch?v=DETcII4Zh_s

I never knew you could use that method in the US (Europe mandated a means to bypass years ago) Thanks dude
