2006 Jetta TDI alive and well but engine cuts off occasionally at stops

Wondering if anyone can help me diag or resolve an issue with my engine dying when coming to a full stop. Older 2006 Jetta TDI with 150k on it, regular maintenance and replaced timing belt and all that inline with that most recently as well as my glow plugs. Everything has driven well for months now. However, after driving for 10-15 minutes my engine will cut off almost every time when coming to a full stop. Starts right back up but I know that's not good for her. Any ideas? My first thought is to increase my idle RPM and see if that has any effect but guessing that'd just be a band-aid as I haven't adjusted it down or anything.
