Ran (nearly?) dry, now stalling in first gear

Hi there
Ran my 2012 R3 Roadster almost dry, but then it may have gone totally dry when I was waiting on an incline bc it stalled. Have had it stall 4-5x more times at low speed in first or even when in neutral. Wondering if I could have had some tank bottom grit enter the fuel filter and now it’s stalling at low speed in first gear? Any thoughts? It’s a bit concerning having that happen on the road.

On your next fillup drop a bottle of Seafoam into the tank to clear the fuel system.
