why wont my car stay running??
 

i have a problem im hoping you can help me with...when i go to start my stang, it starts right up and sounds fine, but as soon as i let it out of the start position it stalls out and will only stay running if i hold it in that position..can you please give me some ideas what might be happening..thanks

Have you added any new elec. parts or taken any off? Did this just happen?

It sounds like you likely just changed or added something and somehow got an ignition signal hooked to the wrong side of either the starter selenoid or the ignition switch ?? or somewhere that you lose power when you let off the start position.
