My wife ran the SC2 (1999) out of gas a couple weeks ago. She did it
again the next week and now today it "ran out" on the freeway. She got
a splash from the highway helper, went to the gas station, and it only
took 5gallons to fill it. (the highway helper didnt dump more than a
half gallon in it)

What's going on? Is the fuel pump failing from running out the first
and second times? Why stall when there is 1/2 a tank?

perplexing..
