Jeep is in running motion, and suddenly the engine turn off.

What is your question?

there is no code appearing on the dashboard. It started to happen 3 weeks ago. Car mileage is 152,000. I did some shop works. Replaced alternator and belt; did engine tune up; fuel hose and tank clean up. still it is happening.

What makes this problem better or worse?

It is happening more often while I m on stop and now while I'm in motion
