driving on freeway car just shut off wont start

Hi thanks for answering my question. I will check the fuel pressure. No the engine didn't over heat. I recently replaced battery and alternator. Then we had the timing chain cover loose a bolt. Put a new bolt on the cover. And the leak stopped. A couple days after that (Friday on the freeway) the engine just stopped. Towed it home later that night it started up again. Drove a about a mile and boom shuts off again won't start. Next day started up no problem drove it home. Its sunday now and started right up. Drove a couple blocks boom wouldnt start. Waited about an hour started up drove to gas station put gas boom it started up. Before I drove out of the drive way it stopped again. Towed it home. This morning started up but decided to leave the stupid car in the drive at home today. Any other suggestions would be great.

Was it the cam or crank sensor
