I think it's say: "I'll come for a limit of time?" but I'm unsure about this

translation
What's the meaning of 制限時間 来ちゃうから?
I'd translate this as "Because the time limit (will) come".

My hunch is "It's about time" or "It's high time".

Then, grammar

"ちゃう" is a verb used in casual speech of "しまう" which is often used for
unintended actions.

Therefore "来ちゃう" means as same as "来てしまう”.

Hence, I guess it means when you are talking with someone else

"We need to hurry up. The time limit is coming."

or in your head

"I should hurry up. The time limit is coming."

But, for sure I need more context to determine what this sentence wants to
say.

Hope it helps.

You could use:

> 'time is almost up' or  
>  'time is running out' or  
>  'time will run out'

for more natural English depending upon the context.
