Lost i2c signal, Arduino stuck

Hello,

I bought a Infrared temperature sensor that is communicating with arduino uno via I2C.
But sometimes the arduino is losing the signal. This happens when the connector doesn't make a good contact.
i'am not able to improve the connector or solder it.

When the signal is lost for a very short time, the arduino is stuck. It doesn't do anything until i reset it.
I want that if the signal is lost, the arduino will try again.

Is there a solution for this?

#include <i2cmaster.h>

void setup(){
	i2c_init();
	PORTC = (1 << PORTC4) | (1 << PORTC5);

       Serial.begin(9600);

        delay(1000);
}

void loop()
{
    int dev = 0x5A<<1;
    int data_low = 0;
    int data_high = 0;
    int pec = 0;
    
    i2c_start_wait(dev+I2C_WRITE);
    i2c_write(0x07);
    
    i2c_rep_start(dev+I2C_READ);
    data_low = i2c_readAck(); 
    data_high = i2c_readAck();
    pec = i2c_readNak();
    i2c_stop();
    
    double tempFactor = 0.02; 
    double tempData = 0x0000; 
    int frac; 

    tempData = (double)(((data_high & 0x007F) << 8) + data_low);
    tempData = (tempData * tempFactor)-0.01;

    float celcius = tempData - 273.15;
    Serial.print("Celcius: ");
    Serial.println(celcius);

   delay(1000);

Since your posted code is incomplete, no.

Why not?

ok, i've posted the whole code in my first post.

I'm using it on a off-road vehicle and the sensor has to be removed very often.
so i'm looking for a software solutions.

ok, i've posted the whole code in my first post.

Well, then I posted the whole answer in my first reply..

I would fix the connector. But if you can't, take a look at how the I2C scanner program for Arduino works. It tries to communicate with a device at a given address and if no answer is received, moves on. You could adopt that approach.
