Find out what you are missing, when the problem occurs. Have a helper crank it while you visually check for spark at the plugs, anything?

You have to test when problem occurs. You can pull spark plug boot, use known good spark plug or spark 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. Any applicable trouble codes?
