That's very true! Haha. Thanks, I'm getting ready to get in there greazy knucks. Replace all the wires (all 6 of them) and check out maybe replace the injector pump. Also, that hose on the lifter pump that shop replaced. Still leaking, smh.. At least the hose is the easy part. I'm going down in there anyway, the head gasket needs replacing.

Now I've got time to go all in there and I don't need it running for a while. Just gotta save some money for now. That shop cleaned me out, and then some. I'm in debt to my Dad. Hope it's worth all the trouble because I planned to keep this van a good while. If it needs a new motor I'm just gonna sell it. It would be more worth getting a newer van. Only because if I'm gonna do that much work to the van I'm gonna wanna go all out. And if I'm going all out, I'm only going to do that to a bigger truck. That was my plan all along, but I didn't want to start doing that for several years. Can't afford it right now.

My guess is that you have a bad fuel hose before the lift pump. Maybe the rubber hose on the lift pump or somewhere closer to the gas tank. When the engine is running, those hoses are under vacuum and it's easier to suck air than it is to suck fuel. The air fills up the fuel filter housing and then kills the engine. Have you pulled off the fuel filter when the engine stalls to see if it's full of air or fuel?

Could there be water in the base of the IP at a level that gets sucked up when driving over rough terrain?

That's my guess

Both times it was completely full. Spilling out before it was unscrewed all the way. This is why I'm so confused. Everything that would make sense, has been checked and seems to work fine. Other than the fuel leak. But again, the filter is completely full. Which is why I'm taking it apart and checking everything. Replacing all wires and bad hoses. Hopefully I can find something. And I do need to replace head gaskets anyway.

Now that I think about it; there is no pipe to suck the fuel from the middle or bottom of the filter. It pulls clean fuel from the top. So any air that gets into the filter either goes into the IP or it gets pushed into the return line back to the tank. The filter will always remain full unless the drain valve has a horrible leak.
