2018 250 Pro XS dies when idling
Ser# 2B529236
Motor will run out of fuel if I idle a good a distance. Pump primer bulb up and it'll crank right up and idle again until the vst runs out of fuel again. Motor runs perfectly and doesnt run out of fuel at a fast idle or wot. I've changed the primer bulb and fuel filter. Still having problems.

Rebuild the pulse pump
Check tank vent or Fuel Demand Valve
Check all hoses for vacuum leaks

Good advise above. Have seen a few "weak" pulse pumps with these symptoms recently.
