You need to do some testing when the problem is ongoing. When problem occurs, if vehicle cranks good but won't start, have a helper crank it, while you check for spark at the spark plugs. If you have spark everywhere, use a gage and check fuel pressure.
Check for applicable trouble codes. Some of the national brand autostores used to check codes for free.
