My first thought for a solution of your problem is plug wires. You have replaced some common problem areas for this situation but the plug wires are the most susceptible for causing a miss after engine is warmed up. Try replacing the spark plug wires and let me know what happens.

You probably have a clogged up exhaust system building backpressure on the engine. Check your mufflers and catalytic convertors if you have them something is restricting the exhaust.

Platinum (or more precisely-AC Delo Iridium) spark plugs. The six spark plugs are directly under each of the six coils on top of the camshaft cover. The air intake needs to be removed, then each of the 10mm bolts for the individual coils. The coils can then be removed and the spark plugs accessed.
