Recently changed out my water pump and put new plugs in it. When I have it idling it runs beautiful. When I put it in gear it dies but only after the motor is warmed up say 10 mins. If I put it in gear at the lowest setting it will stay running but not great. If I throttle it up either in forward or reverse it stalls. Any thoughts? Thanks

Thanks. One question is why won't it do it when I have it running in a trash can? Is it due to exhaust pressure ?
