I'm not sure how to help, unless you do some testing. When the problem is ongoing, if it cranks good but won't start, have a helper crank it, while you visually check for spark at the spark plugs. If you have spark everywhere, use a fuel pressure gage and check fuel pressure. With intermittent issues, you have to test when problem is ongoing.
There may be some trouble codes in computer memory? Some of the national brand autostores will check codes for free.
