Sounds like it's time for a wiggle test. Might sound funny but here is how you do it. Hopefully you have an idea what you're looking at when you're under the hood. ( Not trying to insult you ). When the car is running, just wiggle the plugs by the ignition, fuel connectors and any place you see a plug. If there is a loose plug that might have been pulled apart during the last service, you might find it and just push it together. Try the same with it not starting, you might have someone in the front seat to start it for you after you wiggle something. The problem sounds like it could be a simple electrical issue that rears it's ugly head once in a while.

I have the same problem, it is the the fuel pump wiring harness, the plug end that plugs into the fuel pump. It needs to be tight , the catch on mine that keeps it tight to the fuel pump is loose.I have tried to find a new end to replace mine but have had no luck so I keep it together with vise grips but am not able to put my back seat in..
