Two-party question

What is it about the US's three branches of government that has led to a two-party system throughout the US's history, where nations with two branches tend to have a robust multi-party system?
(Where by "two branches" I mean the Executive and Legislative merged into a Parliament and the head of their majority party is the prime Prime Minister. If there's another name for this style of government, I'd be curious to know.)

This results in a multi-party body because small third parties, like the Independent Party that saw Ross Perot take 10% of the vote in the '92 Election, gain seats and thus political power with the potential to swing votes.
There are of course cons to the system. Parliamentary systems can be afflicted with frequent 'crises of confidence' when coalitions of many parties fall apart. Israel has seen several governments over the past two years, for example, as the Kadima-led coalition failed to preserve its power after a transition from one prime minister to his replacement, and I don't expect the current Likud-led coalition to last particularly long, either.

i'd guess that the factor in these cases is that the parliamentary system allows minor parties that can build enough regional strength to get a few members in the house still have a chance at joining a coalition and influencing the choice of head-of-government, while the fact that the president is elected directly here means that even if you can get enough regional support to pull a few house seats, you're basically cut out from influencing the choice of executive, and will just end up being the hated spoiler party.
