When the problem occurs, if it cranks good but won't start, have a helper crank it while you visually check for spark at the plugs. You carry a known good plug or spark tester in the glove box, won't get hot. Wear gloves, pull a spark plug wire, stick tester in the boot, ground metal part of tester to metal part of engine, engine cranking, watch for spark. If spark everywhere, use a gage and check fuel pressure. Be careful about spraying gas all over a hot engine, safety is your responsibility. Some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one. Any applicable mil codes?
