running it close to low on diesel could have clogged the fuel filter.
also, search for "cone of death" on this site. The fuel pickup in the tank has a habit of causing serious fuel delivery issues.

filter light indicates a vacuum being pulled on filter buy the transfer pump in the IP this means you have a plugged filter or a plugged fuel line between the filter head and tank, if it has a factory lift pump could have crap in lift pump lines or bad tank switch or plugged fuel line at tank switch some thing is plugged...fuel flow problem making it surge...

surge is the injector pump running out of fuel. the filter light is injector pump drawing a vacuum in the filter like was already said.
i would get a portable fuel can and connect it directly to the lift pump. once you see it running good with no filter light there, start moving back toward the fuel tank. sooner or later you will find where the blockage is.
or you could try blowing out the line from lift pump to tank with low pressure compressed air.
but blowing out the line is a temporary fix, because whatever is in it will probably only get sucked back in.
