No power won't hold idle - 1991 Honda Civic

Stalls. (hot engine, cold engine, both?)_what engine of the many.?
lost engine power. sure that will stall any motor.
ever tune it up r, or do the 60k mile service points, EVER?
if car was serviced, we can then say
Stalls.
1: lost 12vdc to EFI and spark , did dash lamps all go dead at stall.
can you save the stall with a fast right foot. (big clue there !!!)
2: lost compression hot. (guage it)
3: lost spark. (tests)
4: lost fueling, or floods more simple tests, ask if not known.
5: EGR main valve stuck wide open.
6: ISC stuck closed but will not stop power, or fast right foot.

lost fueling can be just the skippped, 60k fuel fuilter swap.
