I would think about making sure the ignition is up to snuff before I worried about fuel pressure or check engine light. Use either double platinum plugs or plain copper plugs..... single platinums are a waste of money on wasted spark ignition systems. Inspect the plug wires closely for abrasions, swelling and lightning strikes. Check the boots for splits and carbon tracks..... likewise, use a strong light and inspect the coil towers for carbon tracks.
If you're bound and determined to check fuel pressure, be absolutely sure that you check the pressure WHEN THE PROBLEM IS HAPPENING....
I think that your mystery CEL will vanish when this problem is addressed.
