Engine cutting out

[Tristar]

At WOT my 70 evinrude cuts out. I have just had it tuned due to the engine was running rough previously. It now runs great but after a period of going at high power it starts to cut out. After I reduce the throttle for a while and pump the bulb it is fine for awhile until it does the same thing. Would anyone have an idea what the cause could be?<br /><br />Thanks

Start checkin' the fuel system for leaks. Check any hoses that may be hard and lose at the connections. Check the primer bulb for valves that have come lose. Does the primer pump up OK? Make sure the fuel tank is venting. Check any filter in the fuel system for pluggage.
