Default 92 Mariner 150 Idles, but no power on High

I was crusing at full throttle when all of the sudden I loss power and it came to a halt. It will start and idle. I can give it a little gas and it took me back to the ramp...vibrated, but it got me back. Brand new fuel pump last year. I haven't had a chance to look into it, but I'm assuming a fuel pressure problem. Any ideas? Only thing I adjusted a few weeks back was the idle screw...cranked it up about 1/8 to bring up the RPMs up a bit.

Do a compression test.
Check for spark on all 6.
Check that all carbs are full of fuel.
Then you can start troubleshooting.
I would be leaning towards ignition if it happened all of a sudden. Possibly the high speed side of the stator or a switchbox.
