My car seems to cut off at times after driving for 30 minutes to a hour and starts back up sometime. But when it does not I tap the fuel pump relay in the trunk and it starts right up, no check engine light come on.

Good morning,

I would start by checking the fuel pressure when it does not run. Good chance that it is fuel delivery.

If you tap on the relay, start by changing the relay to be sure it is not the relay. There have been issues with the fuse block that could also cause this issue.
