This is a fuel pump failing. We can confirm this by checking the pressure using this guide:

If the pressure is low or drops when this stalls then we are going to need to replace the pump using this guide to help:

I am attaching the process below from the manual on how to replace this.

Please run through this material and let us know if you have other questions. Thanks
