I have a 90 delta 88, I've changed the fuel pump, coil, spark plugs and wires, chaned the 02 sensor, changed oil. And when I drive it shut down, with no warning, if I sit a minute, it starts back up, but sometimes die again, or it turns over but wont start. What could b my problem? Please help me.

When the problem occurs, have a helper crank it, while you visually check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. Any applicable mil codes?

I always check for an rpm signal, without that signal, the injectors won't pulse.
