Been having this problem with my 94 civic dx where it will start no problem when it’s cold but get about 20 minutes of driving and it will start dying then immediately restarting. So far I have replaced distributor, fuel pump, main relay, fuel filter, all spark plugs, and valve cover gasket and tubing gaskets. I thought for sure it would’ve been the main relay but so far I haven’t had any luck. If anyone has any ideas what it could be please let me know or link me to a thread that has had this problem.
The engine is d15b7
