Engine dies when coasting to a stop.

Intermittently dies when clutch disengaged while coasting to a stop. Engine dies more often when down shifting while coming to a stop. 30003

This is not uncommon.  Couple things you can change.  Try this first.  Easiest and may solve your issue.

In Pro Tuning menu, look for Decel Fuel Cutoff (DFCO).  Raise the enable temp to maximum. Effectively disabling it.

If you also have a hesitation when accelerating,  in DFCO return fuel add more fuel, if only when coming to a stop, in Idle Control go to Decel Open IAC where base setting is 0 and add 10 at a time (have to send to ecu and save and switch off etc).
