Default 1990 Honda Accord EX just shuts off? Advice?

My car is in good-fair condition.















On our way home, it just suddenly slowed down, felt a little chug (as if it was out of gas, but it had half a tank), a belt (who knows which one), squeaked LOUDLY,















then the engine just shut off.















We pulled over, put it in park, turned it on, took a few seconds and a little rev'ing to get it to turn back on.















It seemed like it was going to do it again, but we pushed the gas a little bit to keep it going.































I hope I explained it good enough.















Has anyone else had this problem?















Or does anyone know what it could be?















Is there anything I can try to see what it is exactly?















Thank you.

Good description! The slowing down and chugging almost certainly means you lost fuel pressure - ignition failures or injection quitting is like turning off the ignition switch; it fails so suddenly it jerks.































The top suspect based on frequency of occurrence is the fuel pump relay, called the main relay. Located under the dash above the driver's legs and bolted down way at the top, it is a fairly easy DIY replacement for small and limber people. It is easier to pull the guts out of the old one and stick the guts of the new one in the housing than to try to unbolt it though. The only misgiving I have is that the relay more often gives trouble in starting than while driving but if your relay has not been replaced yet I definitely recommend getting a new one in there.































The next suspect (and even better to change out on general principles) is the fuel filter. Although not as troublesome as the main relay the symptoms are an even better fit - the filter blocks with debris, then when the fuel pump is turned off the debris falls away and lets it go again.































If you are handy with tools and a soldering iron the main relay can be fixed rather than replaced. The details are in the first source. And if you have more time than money (very common these days) and are DIY minded the fuel filter can even be flushed out well enough to stop this nonsense if it is responsible.
