You would need a scan tool to diagnose the system. You could have a computer going bad or a crank sensor or a fuel pump.

would need to check fuel pressure and check for spark when it stalls out.

A couple of common things are the crank sensor down by the crank pulley and the connector going to the fuel pump gets the terminals spread open and will loose connection when gets hot.
