I need help with my car

[wanida]

Sorry If this is in the wrong place to post this. I have no idea what I am doing. I need help figuring out what is wrong with my 240. It no longer runs. When the problem started she would start up just fine but once she got to normal operational temp she would shut off and not start until she was cold again. This just got worse and worse that now she will not start at all. She does not have any spark any more. I have replaced the distriputor, given it a tune up. Im pretty sure you name it. Ive looked at it. I am hoping for freash ideas. My grandfather gave me this car. The least I can do it make it run again. Thanks for helping.
