ok have a volvo 5.0 it runs fine but the last couple of times after run a long ways and coming in to the habor. when pulling up to the dock on a low idle it will die. also when I run it at home to flush it out and it is warmed up the rpm's will go up and down 200 rpm's with out any adjustment from the throttle.
Is the a fuel pump problem or something else ?
the motor has just over 1000hrs on it now .
