Had a simular problem myself, whats your battery voltage when the logging stops you can checkthe log, as i had issues with a voltage drop in my kit car stopping me from datalogging when ever i tried at night due to having the lights on and VTEC engaging.

Also make sure you have resistor type spark plugs.

Check your ground on the thermostat housing. Clean it and make sure it is good and tight.

It is most likely your ignition system. Try returning it to stock including wires.
