Coil ? Relay(s) ? Fuel ?
Your problem is the crank position sensor (CKP) is getting heat soaked. Replace the ckp and your problem should go away. On the firewall near the ignition coil there is an electrical connection bracket which have three wire plugged into it.

Black is the CKP
Grey is the RPM sensor
Red or Brown is the Knock sensor.

Follow the black cable and it will lead you to the crank position sensor.
