why did my 2009 Toyota Corolla suddenly shut off

What is your question?

while slowing down to a stop the engine shut off and will not restart thought maybe it was the fuel pump relay that I can't seem to locate but when you crank the engine over I have power to the pump and now when you try to start it the engine keeps turning over like its stuck you have to turn the key back to stop the engine from turning over

How long has your 2009 Toyota Corolla had this problem?

just happened yesterday
