This sounds very similar to a problem I had. It took at long time to trace
and solve (by trial and error in the end). My problem was the coil. It was
not dead but the spark it was giving at the plugs was not sufficient for the
injection engine. Replacing the plugs etc. masked the problem for a short
while but it always came back. Worth a try not too expensive and easy to do.
