Fuel Starvation?

I replaced the hose from the metal line to the fuel pump inlet with EFI hose. The rear hose looks good, and was probably replaced when the tank was but I have not checked it.

I would. That was what was wrong with my Ford truck. It was doing the exact thing you're describing here, but the hose looked fine from the outside. There was one soft spot in it. Once I replaced it, it was fixed. The fuel pump was sucking the hose shut.
