Runs great, after running a while the engine will turn off and wont restart. If you wait about 15-20min it will start up and run great again for a while and repeats

Start by checking and monitoring the fuel pressure-fuel pump could be failing

Have it scanned for codes while the problem is occurring. Check spark when the problem is occurring. Check the fuel pressure when the problem is occurring. Make sure the injectors are being properly pulsed when the problem is occurring.
