Will not start without starting fluid

You are in the right area, but I have a better suggestion to consider. The fact the engine ran okay for ten minutes suggests the fuel filter is not plugged. A plugged filter would cause the problem right away. Your description also does not sound like a failing fuel pump. The better suspect is the screen on the fuel pick-up tube in the gas tank. The contributing factor is sitting for an extended period. Mold feeds on the alcohol in ethanol, and that mold floats over to the screen when the pump is running, and plugs it. Another symptom to look for is the engine will have the biggest tendency to stall when the largest volume of fuel is being pumped, which is during coasting from highway speed.

Also consider connecting a fuel pressure gauge and hooking it under a wiper arm so you can watch what happens to fuel pressure when the problem occurs. Typically, with a plugged pick-up screen, you will see the pressure drop slowly until it gets low enough for the engine to stall.

This article might be of some help too:

Hello, I am Danny.

Sounds like you already answered most of your own questions! I suggest to change your filter first.There is a product called Seafoam you can buy at your local auto parts store to add to the tank to help the old gas burn better until it is out of the system. Most auto parts stores also have a tool loaner program to rent a fuel pressure tester. I would also suggest you check your vans fuel pressure to see how good the fuel pump is working. It should be between 35-45 PSI. I am attaching a link to give you an idea how. Hope this helps and feel free to ask any questions if needed. Thanks for using 2CarPros.
