98 Honda Accord 4 cyclinder 144k miles

For the last couple month, my car would suddenly stop while im driving. All the warning lights would turn on and the engine just shuts off. Recently, its been occurring perhaps every other day. I would shift to neutral and restart the car immediately while im still drifting. So far, I have changed the starter and spark plugs. When I plug in the computer to check for engine failure log, there is nothing. The next thing on the list to change is the relay, is this correct? I do hear clicking sounds and my alarm and door auto-lock also locks automatically.
