[QUOTE] This is getting progressively worse: My partners J reg Astra injection is fine most of the time, in fact every time I drive it....always the story when tying to find a fault isn't it....she says it coughs without warning, totally out of the blue and then dies. Now my thought is either is could be being starves of air and/or fuel. After it's died give it 2 mins and it'll start again. Recent work includes head gasket replaced due to crack, thermostat and cam belt also replaced. It has been into the garage twice and they say they can't find out what is happening unless they experience it themselves...hmmm. Any thoughts on what could be happening? TIA [/QUOTE] Had a similar problem on a honda bike turns out the fuelline to one of the carbs was blocked so the carb ran out of fuel and the engine stopped since it's gravity feed, after some minuted the carb filled up again and off it would go !
