'96 12 valve won't start-think it is fuel problem

[Reddog1]

'96 12V, 190000 miles, auto transmission. Started to idle a little rough (no exceptional smoke) on occasion for the past month.

Last Monday, after a 150-mile trip on the freeway, and about 4 miles in town, in the process of parking, it started to run real rough (no smoke) and died. It usually starts on the first 1 or 2 RPMs. It required several RPMs to start, ran real rough (no smoke) and slow to build up RPM. It eventually smoothed out and ran like it has for the past 100,000 miles.

Ran great for five days (about 500 miles).

I started it today, after about five minutes it started running rough then died. It would not start.

I had a fuel filter on hand, so I changed it. I filled the new filter with fuel. The screen was changed about 50000 miles ago. I had to bleed the injectors before it would start. After it started, it ran great. I went for a mile test run. As I was turning around, it started to run rough. I built up the RPM, and it smoothed out.

When I got home I let it idle. In less than five minutes, it started running rough and died, no smoke. It will not start. Loosen the nuts on the injectors, crank engine, and no fuel.

Any suggestions?

I do not have gauges to put on fuel system to check pressures.

I have 370 injectors, #10 fuel plate, 3K gov springs, marine head gasket, DTT trans and 16 degree timing. I do my own work.

I need the truck for work Sunday.
