Welcome to the forum, 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. If you have spark everywhere, use a gage and check fuel pressure. Also, check for troublecodes, around here some of the national brand autostores will check codes for free.
