I have a 2002 4.2 v6 Mercruiser engine acting up

[Bigshug]

Starts and ticks over , revs and runs smooth as silk from cold but. When I
Put her under load, she cuts out by about 2000 rpm. Then she wont start or does but runs dirty. I need to leave her 10 to 15.mins before she fires and runs smooth again. She seems to be pushing plenty fuel through the primer pump.
ticks
