Need some OMC help on a 1997 Johnson 130.

I'm pulling my hair out on this motor problem.
It's a new to me 1997 130 Johnson.

Fresh fuel on a 6 gallon tank
Compression = 130psi in all 4 cylinders
Checked spark = all 4 plugs are getting spark.

Problem:

Motor starts and idles for a full minute. Then motor stalls out. It will restart right away and run for 10 to 15 seconds and quit. Doesn't appear to be idling rough.

Work Done so far:

Though it might be the fuel primer (Choke/solenoid). Tried moving the red arm to either position. Open position will flood the motor. Eliminated this as possible problem.

Rebuilt/cleaned carbs . . . Floats are adjusted properly (Primer bulb gets hard . . . bowls don't overflow) fuel getting to bowls of all 4 carbs. Didn't find any restrictions.

replaced inline filter.

**********************
Motor still behaves the same way after rebuilding carbs
primer bulb stays full.

At this point I feel like the I've eliminated fuel delivery and now believe the problem is ignition related . . . Any advice on where to start? Could this be a bad Powerpack?
