i say main fuel relay as well. it could cut out under load while hot and then start to work again so that by the time you check it, it says that the main relay is ok. in my 92 hatch when it gets hot and i shut off the car, the fuel pump doesnt kick on right away till the relay cools a little bit. kind of embarrassing getting gas when your car doesnt start. i put in relay and car works fine now.
