What year MBP?

How do you know you recharged it?

Ultra-Low Power Deep Sleep 

The most likely cause of the power problem is a dead battery. When your Mac's battery charge is extremely low, the computer goes into standby to prevent losing your work.

When the power comes back, so does your device. However, it might take a while to charge the battery. Plug your MacBook into an outlet that you are sure is working and wait at least 10 minutes before trying your Mac on battery power again.

The MacBook may display a black screen during this time, which is fine. It may also display a dead battery icon, which is even better. That indicator goes away after you charge the Mac's battery.

it sounds like you should try booting into safe mode

Reasons a MacBook Pro Won't Turn On 

When a MacBook Pro doesn't turn on at all, the problem is often related to the power from a wall outlet and the cable that supplies it to the Mac or its battery. However, there are other possible culprits.

How to Fix a MacBook Pro That Won't Turn On 

Press the Power button on the MacBook Pro and listen for sounds from the fan or humming or whirring noises. If you hear anything or see lights on the keyboard, your Mac is starting up just fine, but your display has a problem that may require professional help. However, if you hear and see nothing, these fixes may get your MacBook Pro back up and running.

1. Check the power connections. If your MacBook Pro won't turn on at all, then the first thing to check is that it's plugged in. Wait a few minutes before turning on the Mac again. Don't forget to check the power outlet with a lampor another device to make sure the outlet functions correctly.

1. Swap out the power cable or adapter. If the Mac is plugged in and doesn't turn on, the power cable may be faulty. Swap it with a known working cable to help pinpoint the problem.

1. Charge the battery. If you run your laptop on battery power, the battery may be dead. Plug in the laptop and wait at least 10 minutes while the battery charges before starting the MacBook on battery power. If you can't charge the battery, take the MacBook to an App Store or an Apple Authorized Service Provider for a replacement battery. Here's how to go about replacing your MacBook Pro's battery.

1. Turn up the screen brightness. It's possible the MacBook Pro is turned on, but you can't see it. Press the F2 key at the top of the keyboard to make the screen brighter. On MacBook Pros with the Touch Bar, the brightness control is on the Touch Bar, If the Touch Bar isn't lit up, the MacBook Pro isn't turned on.

1. Remove all accessories and peripherals from the Mac. A problem with a printer, external drive, USB hub, or mobile device—or one of the cables—could prevent the Mac from starting.

1. Reset the System Management Controller (SMC). The SMC controls much of the basic functionality of a Mac, from its display and lights to its fan and Power button. Resetting it sometimes resolves whatever stops the MacBook Pro from turning on. The method differs for MacBook Pros from 2009 or earlier or for the recent MacBook Pros with the T2 security chip.

Sorry for the long reply

PS

I bet it's a power outlet or loses connection.

if not and the MBP is older than 2017 ish there is a very good chance that the battery is recalled check the SN with Apple

also, my MBP has been able to start with a dead battery it's very unlikely if the cord has power that the computer's battery is the problem (it can happen) it's just very unlikely that you can't use wall power to get it started.

try a different plug
