Not really. God having rules and tending not to break them is not a restriction on omnipotence in the sense of 'can't' but rather 'won't.' God also binds Himself in terms of covenants, as for example a promise not to bring on a deluge again that destroys everything. God's rule breaking tends to be for a particular purpose. Raising Lazarus, for example, was meant to inspire faith. But rule breaking is rare and seems to require faith in turn since it is unlikely you can persuade God to do that again in your presence just to check up on His capabilities. So, you must accept the testimony from a long time ago that that miracle occurred.
