my 93 prelude was doing the exact same thing and for me it was my alternator was working properly.
go to a parts store and have them test it.

hey sounds to me like it's the alternator see when the alternator is not working properly the main source of direct energy comes from the battery and when that runs out it makes your car die . then it might turn on again but it does not last. u shuld have you alternator checked to make sure if not ask me again..

i have the same car as u do, and something lie this happened to me. check ur spark plug wires, and ur distributor cap.. check the coil itslef too. This happened to me because my spark plug wires werent sealing tight enough, and there was some "moisture" going on in there.
theres also the possiblility of the alternator being bad.. try turning ur car on with another battery, and once its on, unplug the battery.. with the car on. if the car just dies.. its gotta b the alternator

SOURCE: 86 prelude 2.o SI has no spatk and no PGM-FI light. how do I test the circut for that light

if you have changed the distributor cap,rotor button,spark plug wires and plugs and you still dont have fire then its most likely your distributor.first check the fuses or relays if you have replaced those items.
