Engine shut off during mid drive

Hi guys, I am new here and having some problems with my car on the registration card shows model as E-CB1 with F18A engine. I am having this problem when the car's engine suddenly shut off in the middle of driving ang refused to start. After waited for half an hour or more it can be start again. I have changed the underhood fuse box, change the distributor, the spark plugs and the car is back to normal for about a week. Now it has happened again and worst is the timing is below 1000 rpm at idle. The car is using single carburator not fuel injection type. Please advise me of what should I do to solve this problem.
Thank you in advance

P.S. The pictures are before I change the fusebox
