Haavard,

I think with the information that you have supplied, indicates an engine
electrical management system problem.

Could be can of worms, could be simple, but with your description----who
knows?

I suppose I would take the time to take a compression test, prior to
making any judgements.

I think this might be a good as any place to start anyway.

Later,
