I have 1965 75 horse evinrude speedifour v4. Engine starts and runs good at low rpm but will die after a minute or so. Will also die if accelerated above fast idle.

Those symptoms would be consistent with an air leak.. Try pumping the bulb. If that keeps the engine running, Work your way from the tank including Pickup screen, anti-siphon valve, bulb, and all connections up to the fuel pump.
