rst:0x1 (POWERON_RESET), boot:0x13 (SPI_FAST_FLASH_BOOT)

Hello everyone, we have a board (designed by us) with an ESP32 (just the module, not the development board). In random moments, the microcontroller resets and throws the next text error:
rst:0x1 (POWERON_RESET), boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00, d_drv:0x00,cs0_drv:0x00,hd_dr...
mode:DIO, clock div:2
load:0x3fff0030, len:1184
load:0x40078000, len:13132
load:0x40080400, len:3036
entry:0x400805e4
The code is implemented in Arduino, we use a SIM800 (for HTTP), a GPS neo 6m, read pulses from a sensor, control six displays (7 segments) and one LCD 20x4.
We couldn´t find helpful information about this error and don´t know how to solve this. Any idea will be great.
Thanks!

Its temporary power loss or EN pic connected to GND.
