It's probably best to keep the pump covered with gas, no matter what you drive. Don't suspect a fuel pump issue without using a gage and testing fuel pressure.

To add to JDLs answer, in tank fuel pumps are cooled and lubricated by the fuel in the tank. When you run a car out of gas, it pumps a lot of air through the pump which overheats it and causes some severe wear and many times, failure when they cool off.
You will need to use a fuel pressure gauge to verify this
