hey, i just did a cam and head swap on my car and it wont stop dying. it will start up and idle fine and then when it warms up it just shuts off and i can sit there and crank it over and over and it wont even put out a spark. i let it cool off and it starts right back up no problem. could this be my ecm getting hot or my crank shaft position sensor getting hot??? any help would be great.

 

it was the crank shaft sensor thanks for no help
