99 accord lx 333,000 original miles lately the car unannounced wants to die on me everything just turns off, car has no cel or mil I ran an obd test on it and gave me 0 codes I've had both o2 sensors replaced the cat converter and egr valve, car idles fine car runs and drives fine but just randomly shuts off ill start it back up and its fine but more recently its taking me 3 or 4 times of trying to start it before it'll actually catch and start up. I'm boggled by this issue car has drained my pocket for 2 yrs now I just dont know what's going on with it...any suggestions?

 

A few possible things - test them - come to mind.

Electrical part of the ign switch.
ICM - Ign Control Module
PGM-FI Main Relay - relay controls power to the fuel pump.
