Check your fuel pressure when it starts to cut out. Sounds like fuel pump starting to go bad to me.

Fuel pressure is where it should be.

A really easy check:
There is a gang of wires coming up the front of the engine that run up around the manifold heat shield to the injectors. (at least there is on my 90). The edge of that shield can cut into those wires, sometimes causing all sorts of intermittent problems.
