Hello, I will try my best to give you my suggestions on possible causes. Please understand I am not standing in front of your vehicle so diagnosis will be a educated guess at the most.

There are several possibilities:

losing fuel pressure-weak fuel pump

losing fuel pressure-weak or intermittently failing fuel pump relay/main relay

lose, worn timing belt

ignition switch contacts worn causing intermittent starting issues
