The fact it’s happening as it heats up says to me something is breaking down, now it could be any number of things the first being the coils, I however would check & clean as many connectors as you can find, the efi systems no matter how clever they make them out to be work primarily on resistance so a bad connection heating up cause more resistance then leading to wrong signal to the ecu.
