Hey guys. I have a 96 civic si with a b18c1 swapped in. The car runs and drives perfectly but sometimes all power to the engine gets cut and after a couple minutes it can start it back up and drive off. A couple months ago it got to the point where every 5 minutes it would die even just idling, and now it's just really random it could die after 5 minutes or I could drive around fine for an hour. I've replaced the fuel filter, fuel pump, and main relay but that didn't fix it. Any advice would be welcome. Thanks.

 

Are you getting any cel codes? What ECU are your running?
