Overheating and unable to boot,stuck at progress bar.

MacBook Pro, 13inch, early 2015.

It was running fine and well,till today morning I opened it,opened a tab in Safari,had to immediately run for an emergency so couldn't shut it down,just closed the lid. Have done this before,sometimes left it like that overnight. Anyway, returned after like 3hours and it was toasting hot. It was on,but there was nothing on the screen. So I shut it down. Tried turning on,logo comes,progress bar comes,and remains stuck at like 5% of the bar. I tried everything under the sun,all with same result, except on a NVRAM reset,the progress bar shows progress done till 100% of the bar,albeit slowly,but doesn't proceed any further, I've left it for almost 2 hours. The other one was the apple hardware diagnostics,which said everything was fine. I've run the CMD+v but it gets stuck at some error that I don't understand at all. Also, everytime I open it,it heats up like crazy. My memory was a little more than half full,if that's any help. Anybody help please?

It would help if you told us as much as possible about the error. Is it a gray screen with multiple languages?

"CMD+v" doesn't seem to fit this situation - do you mean command R for Recovery mode?

I have done this,and I was unable to understand ..it showed something like ACPI error and I have never used windows on mac? And then 'system uptime in nano seconds'..and then nothing..so I can't even exit because nothing gets typed and I have to do a hard shutdown. Really at a loss.

So i left it undisturbed the whole night,and was going to take it to a repair centre, but when i turned it on today morning it was working just fine. Guess my mac needed some time off? But its behaviour is getting more and more uncertain. I dont understand what could be causing these problems. I would've taken it to the genius bar if there was one here, but there are only apple authorised resellers who always give the same solution 'change the logic board'.

CMD+v for verbose mode. I tried recovery/safe modes but it's all the same. The usual black screen with apple logo. But the progress bar is stuck.

So this is max that happens even in recovery mode using CMD+opt+R . After the globe thing,the same old apple logo.except that the progress bar shows 100% . But doesn't proceed from there at all.

As per this article : Start up your Mac in single-user mode or verbose mode - Apple Support

Use the command written in the third point to exit .

From the link you provided I remembered CMD+opt+R was the recovery mode I used when I reinstalled my OS,andso I tried it now. It's showing the globe logo, let's see. I'll update soon.
