Welcome to the forum, you need to do some testing, when the vehicle refuses to start. Have a helper crank it, while you check for spark at the plugs. Pull plug boot, stick known good plug in boot, lay metal part of plug to metal part of engine, engine cranking, watch for spark at tip of plug. If you have good spark everywhere, check fuel pressure. If your tbi, look for an injector spray pattern, engine cranking? If no spark and no injector action, when the problem occurs, I'd look for an rpm signal. How long since a tune-up?
