The engine runs fine at first start up. After an good run the next time you start it the engine runs strong then cuts out likeit is starving for fuel. you can run above idle but if you give it too much throttle it bogs down. I pump the bulb and it will run for a while then it all sttarts over again. I changed the primer bulb but no difference. I am thinking a pin hole in the fuel line causing pressure to drop. Any ideas before I tear the boat and engine apart?
Fuel pump diaphrams need replacing.

If you have not changed your fuel filters i would take a look at that as well. My 250 did almost the same thing as what your's is doing.I took mine in and had the computer hook up and i was told it was a fuel restriction.So i replaced the filters and now its running good again.

Unbolt your pumps a little bit and pump your primer bulb. If fuel comes out of your fuel pumps then the diaphams are bad. You can get them at iboats.net pretty cheap and it's a simple fix.
