If the cause is not from any sensors or signals for the PCM, the Check Light would not show.
Items at fault that does not show on the CEL.
1. Ignition coil.
2. Ignition switch. (Power supply interruption).
3. Fuel pump or relay.
4. Distributor cap, rotor, cables and spark plugs.
I would suspect it to be an electrical fault so that is where you should start when it occurs.
