Don't replace the TPS, that isn't your problem. This sounds more like an ignition switch or part of the ignition/starting circuit. Don't start replacing parts, take that money and pay a shop to diagnose this for you. Tell them you wish to make the repairs if you want to save money, just be careful, too many people spend much more trying to do it themselves rather than have a professional do it.
