Idles good,seems to run good for about 60 sec or so from start to full throttle then bogs out and has no power till you lug it around a but or shut it off then you get about 60 sec of full throttle running again. I know nothing about Outboards but was a motorcycle mechanic for 8 years,so I have Mechanical skills. I would like to hear some ideas of things to try. The fuel line is clear and I don't see any leaks(air or gas). I haven't messed with it much,just took it out today for the first time in the water and this is what it was doing.

Sounds to me like the carbs fuel bowls are emptying quicker than they are being filled. Will pumping the fuel primer bulb keep her running? If so, fuel pump needs attention.

What about choking it? Spraying pre mixed fuel into the carb throat? If that keeps her running, the carbs need a bath/rebuild.
