I've got the same car, a 2002 Astra. I just found out that I can overfill it with engine oil, because this Ecotec motor is designed for 1 litre of engine oil only. If someone overfills the engine oil, it starts having electric issues. Last time my mechanic loaded too much engine oil, and the engine started leaking oil from every joint.

If it's on an incline, perhaps your fuel tank may need cleaning for sediments. Is your car an automatic? There may be a sensor that detects if the car is on a slope on the gearbox.
