Q: Not Changing From E Mode To Hybrid

The illumination of the check engine light tells me that vehicles computer has picked up a fault which may shed some light on the problem causing your stalling concerns. Typically it is not good practice to run a vehicle too low on fuel as the fuel lubricates and cools the fuel pump while it’s operating. Too low of a fuel level may starve the pump and cause damage. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer inspection of your vehicle to read the check engine light codes and perform a few tests to offer a more personal diagnosis of the issue at hand and estimate the proper repairs.
