When the problem occurs, If it cranks good but won't start, have a helper crank it while you check for spark at the plugs. You can carry a known good spark plug or spark tester in the glove box, they won't get hot. Don't pull spark plug from engine. Where applicable, if the plug wires are hot, use glove to pull spark plug wire. Stick tester in plug boot, ground metal part of tester to metal part of engine, watch for spark engine cranking. As far as checking fuel pressure, use a gage, don't let gas spray everywhere, fire hazzard.

Check for applicable mil codes, you can check those yourself. Any codes?
