Can someone help me?

Car starts fine and runs but after I drive to about 3
to 4 places it wont start up again and I have to wait
for about 30 min then it will struggle to start then
wait 10 more mins and it fires right up. I have
replaced injectors, fuel rail pressure sensor
seemed to fix it for about a week then back to the
same. I've done a full tune up. I've replaced the
throttle body because the only code it throws is for
the throttle body. HELP.
