Ok slow down, it stalls, that is all we need, no need guess.
and tune up don, but you skipped the fuel filter? and air filter,?
STALLS 101.
1: lost 12vdc to EFI system. lost elect. power. easy to test , easy to see. you can attach a DMM set to 12v at the IGN output wire.
and see if it drops to zero as engine dies. sure can.
2: you could , check for spark at death, got spark
and work that path if spark fails.
3: lost fueling, (sparks soaked in fuel x 4? ) then its flooding
if dry spark tips x4 then lost fueling , so try test fuel.
you failed to say, is this a hard fail , i t dont run now.
or is always random... just a lil hint.
assuming power is hot at all EFI fuses.
then fails only 3 ways,
1: lost compression hot (if solid lifters, lash never set)
2: lost spark'
3: lost fuel or flooding.
if flooding use WOT, in this super secret mode works, Wide open throttle cranking, clears floods. (ecu cuts all fuel in this mode)

There is a relay mounted way up under the dash on the driver side. It
is about 1"x1"x2" and it says Mitsuba on it. This is the PGMFI relay,
sometimes called the main relay or fuel injection relay. It is very likely the problem. You can buy another one, or there was a bulletin on how to repair it. You need to take it out, pop the cover off, and resolder the cracked solder joints on the pc board that the relays are mounted on. Really not that hard if you have a little soldering experience. If not, just buy another one, about 50 bucks.

Check for fuel, sound's like not getting fuel.
Distributors are a common failure item when it comes to Hondas wether it is the coil, the igniter. Replace the distributor assembly if you have already ruled out all other possibilities such as crank sensor, timing belt...
