i think you need to keep a closer eye o the table you're at ,and adjust your play,if you can't steal,don't try,if it's easy to steal,do it lots!
i play a variety of buy ins,and sometimes the lowest buy ins are extremely tight,because of there budget,and sometimes,you get in a room of people who are just wasting there buy in,and having fun,while playing in another more expensive tourney,which i do also.
really you need a variety of strategies,for each type of room you are playing in,sometimes it's stealing a raise from a loose player when you have position,which sounds like what is happening to you at times,and sometimes you have to lay low and wait for a monster.
if you're going into the second hr alot with less the 2k in chips,i would think you are playing to tight,since that's the average stack,and that's why it's difficult to steal,because your stack can't break most players.
just some thoughts,maybe someoe else can help you alot more,hope your results improve!
