Intermittent issues can be hard to track. Id have to check voltage and ground at the fuel pump connector, when problem is ongoing. Gray wire is voltage for fuel pump motor, black is ground.

Any applicable trouble codes? Some of the national brand autostores will check codes for free.

If no initial prime could be wiring circuit/voltage or pcm. Also intermittent rpm signal can drive you crazy, engine running. Initial prime doesn't use rpm signal.
