Shut down fix after liquid spill.  Well I hope this helps some people.  So, I bought this 2011 macbook pro on craigslist for $100.  The issue was that it would not stay powered on according to the seller due to a liquid spill so I took my chances.  I installed a new SSD and got it to power on.  Indeed the it would turn on and then power off.  Sometimes it would stay on for hours and other times it would power off before it would even boot up.  The number keys would not work and they typed letters instead.  What was odd though was that most times when it was on it would open the window that pops up when you hold down on the power button and then shut down on its own.  Other times it would shut down with no warning.  Another odd thing is that after holding the shift, control and option button (not the power button) it would reset it self like I did and SMC and then I would hit the power button or any key and it would turn on.  At this point I was suspicious that something isn't right with the keyboard which might be the source of the shut downs.  However, that was a hard fix so 1st thing I did was a new battery.  I was hoping that since it still had the original better that maybe thats why it would shut down.  So I bought a new aftermarket one for $30 but no fix.  So now it was for the challenging mission.  Keyboard replacement.  I bought a new one on amazon for $20 without the backlight since mine was still working.  Once I got everything out I found that the keyboard from the inside is covered with a black plastic cover.  So I am thinking wow, it would really be hard even with a big liquid spill for the liquid to reach the logic board.  To get the to the point, I go the new keyboard in.  Took about an hour and....the Macbook is like new.  No shut downs anymore.  For those that do not know, the keyboard and power button are connected (once peace) so I am sure thats the reason for the shut downs.  Something was shorting out to cause the shut downs.  This was actually not a hard thing to do so don't let it scare you. As long as you don't jerk anything out you will be fine.  I hope this helps some people.  By a new keyboard before you sell your macbook or buy a new logic board.  Good luck!
