Problem found 454 starts runs then rough Idle quits re-starts

[grewvin1]

1984, 454 twins, one engine starts well idle out of marina throttle up engine quits, restarts rough idle.
Replaced carb. filter, replaced fuel water sep. filter, fuel fresh. Will be checking fuel pump press next. Would like to know if the condensor could cause this type of condition? Points new last year set with dwell meter timmig is on. Need thoughts where to go next.

Bad coil, ran boat 3500 rpm for 10 min. then problem started engine bogged and lost power, ran at 1500 rpm, changed out coil and all worked well from then on.
