Sounds like you have a issue with the fuel pipes where it is allowing air into the system so that it needs bleeding before it will start. This would be done while the car is being bump started. It would only need a slight bit of air to be seeping in so that you can run the car all day long happily once started as the fuel pressure would be maintained once running. This would probably just a union which has been opened at some point and now not creating a good seal.

I've had this fault on various cars and almost 100% it's been down to a faulty starter motor.
Elecrtical noise generated by the high current starter motor produces electrical noise that can swap out the signal from the crank angle sensor.
Bad bit is either an ocillisope is neede for diagnosis,not common garage equipment,or swap out the starter.

either air leak on fuel system or faulty crank sensor... does that engine have the seperate fuel ECU bolted to the fuel pump... these do give trouble... they are just plug and play and also dont throw up any fault codes... just a thought..
