Fuel Filter
Good news. The minivan is repaired. Apparently the fuel filter (and fuel line where it goes through the filter) failed and that caused the gushing gas/car stopping problem! $88 dollars later, Andy had us on the road. (I think that is the cheapest auto repair we have ever had with the minivan!)
Since we are selling both cars before leaving on our trip, we were a little worried when the car broke down. Bad timing to have a major problem. Whew!
