Engine cut at idle problem..

Hi,
I wonder if anyone can offer some informed thoughts.

Continental IO-360-D engine cutting after 10-20secs at Idle. Electric pump on, no cut. Also cuts at ground leaned on idle.

Two engine cuts in flight upon idle throttle, fortunately all immediately resolved by fuel pump on.

Thanks in advance.

Without looking at the manual , have you checked the hi and low unmetered fuel pressures, could be a good starting point
