Probably dist connection but here are a few other things to check.
Fuel pressure...pump failing, filter clogged, leaking injector, are you sure FPR is OK?
Re-check plugs for a dirty plug(s)...bad injector(s)
Check knock sensor, unbolt and wrap in rag, If OK clean connections.
Test temp sensor and clean connections.
Bad ground somewhere...clean all to shiny bright and check ground connections and wires at main relay and fuel pump relay near ECU. Intermittent grounds at these relays can cause all sorts of gremlins.
Try a known good ECU.
Try a known good ignition module.
Try a known good APC box and solenoid.
Double check all turbo plumbing for hidden crack/split that opens up under boost
