Okay, so you need to get better at the executive mindset / decision making so that you're not spending too much time on a subset of questions and then messing up the rest of the section. Getting better at timing is part of this; here are some resources to help:

In conjunction with that, re-read the What the GMAT Really Tests / executive reasoning article that I linked last time. Read it every few days. Think about what practical implications this mindset has for how you take the test and even how you study for the test. As you get further into your studies, you'll keep getting more and more out of these thought exercises. Your timing is really ultimately about making better decisions while the clock is ticking.
And here are some things to help with stamina:

Next: the materials you listed. I didn't see the Official Guide books listed there. Is that because you just assume everyone has them / I'd assume you have them? Or are you not actually studying from them? If not, buy at least the big OG. (Note: GMAC is publishing new editions of all of the OG books on June 8th - you may want to wait to buy then.)
Which leads us to: what did you think of the 2nd Level of Study article? How has your study been like what that article describes and how has your study fallen short of what that article describes? (I'm bringing this up because the best place to do this analysis is with official test questions!)
The issues you mention with respect to timing (and, therefore, decision-making) are significant enough that they are probably responsible for at least half of the shortfall between your last test score and your desired test score, if not more than half. So those are your major focus for now. Of course, you can also work on specific content weaknesses as you notice them, but your real goal is to get better at the process of thinking your way through this test.
By the way:
quant FDPs- 700 ,Positives and negatives-700 qns and combinatorics and probability- 600-700 qn
I'm not very concerned about any of these things. The first two are 700+ questions. You can get those wrong and still earn a 700+ score. As for the third category, you will typically see just one of these on the entire test.
Maybe two. Repeat after me: these are not worth the mental energy required to do them (or to learn how to do them)! Blow them off. Worry more about careless mistakes, topics that show up frequently, etc.
Where do you tend to make careless mistakes on quant? Do you have any general weakness areas that are both sub-700
and topics that are tested frequently?
For RC, do you have our 5th edition or 6th edition guide? (I ask because we completely re-wrote RC for the 6th edition.) If you have 5th edition, here is a link to a series of RC articles I wrote while figuring out how to re-write the book for 6th edition.
