I use external harddisk(connected via USB with its own power supply) to boot into dietpi on my raspberry pi. It works okay for a day(even with multiple reboots and poweroff). But the next day RPi sends no power to usb ports and so it doesn't boot.
When I use SD card to boot it works. Ethernet port works and I'm able to SSH. I've plugged my external drive using the USB adapter to another computer and I can confirm that it is working. I am using the official power supply (2.5A 5.1V).
If I try to boot after keeping the RPi off for more than 1 day from the external HDD it works again! But this repeats everytime.
I can't understand this peculiar behaviour of my rpi 3b.
I have also set max_usb_current=1 in boot/config.txt but still no luck.
Here is the output of some of the commands I ran after booting with sd card on raspbian:

uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1
uncomment this if your display has a black border of unused pixels visible
and your display can output without overscan
#disable_overscan=1
uncomment the following to adjust overscan. Use positive numbers if console
goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16
uncomment to force a console size. By default it will be display's size minus
overscan.
#framebuffer_width=1280
#framebuffer_height=720
uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1
uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1
uncomment to force a HDMI mode rather than DVI. This can make audio work in
DMT (computer monitor) modes
#hdmi_drive=2
uncomment to increase signal to HDMI, if you have interference, blanking, or
no display
#config_hdmi_boost=4
uncomment for composite PAL
#sdtv_mode=2
#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800
Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on

Please help me resolve this issue. Thanks :)
