My first guess is ignition pick up in distributor.
I recently ran into a Chevrolet Suburban with basically same problem.it to had the 454 engine. owner had already replaced the coil and pickup in the distributor.
After checking-rechecking and checking again we determined problem had to be in distributor
In the end we replaced the entire distributor assembly and it cured the problem. IIRC a complete new dist actually cost about same money as the replacement parts in old one.
After vehicle was repaired I took the old distributor apart and found the shaft was worn just enough to move (wobble around)and come In contact with parts it wasn't supposed to causing an intermittent
short that would cause engine to quit.
Didn't check it while it was installed but it had very noticeable free play .Movement was easily seen when we compared old dist to a new one .

"Depending on the age & mileage it could ALSO be distrubutor shaft wobble or play. Most stock distributors use bushings & coupled with poor oiling in this area the bushings wear out. You must remove the unit in question & physically push the top of the shaft sideways in both directions to detect any play. if it is loose you can SEE it."
