reset

I am using uVision4 and have an LPC2103.
After each reset the module desn't start directly (after 2 or 3 attempt) can you help me.

I do not think it's a reset problem.
For example:
electroblogs.weebly.com/.../8478695_orig.png

I am beginner in programming in Keil and I want to know if there is a problem with code (main.c or startup) or at target.

int main()
{
PLL_Init();
PINSEL0=0x00000005;
PINSEL1=0x00000000;
IO0DIR = 0xFFFFBFFD;
UART0_init();
IO0SET |= (1<<13);
IO0SET |= (1<<17);
IO0SET |= (1<<21);

while(1)
{
/*
code
*/
}

void PLL_Init(void)
{
#ifdef __DEBUG_RAM
    MEMMAP = 0x2;
#endif

#ifdef __DEBUG_FLASH
    MEMMAP = 0x1;
#endif

#ifdef __IN_CHIP
    MEMMAP = 0x1;
#endif


    PLLCON = 1;
#if (Fpclk / (Fcclk / 4)) == 1
    VPBDIV = 0;
#endif
#if (Fpclk / (Fcclk / 4)) == 2
    VPBDIV = 2;
#endif
#if (Fpclk / (Fcclk / 4)) == 4
    VPBDIV = 1;
#endif

#if (Fcco / Fcclk) == 2
    PLLCFG = ((Fcclk / Fosc) - 1) | (0 << 5);
#endif
#if (Fcco / Fcclk) == 4
    PLLCFG = ((Fcclk / Fosc) - 1) | (1 << 5);
#endif
#if (Fcco / Fcclk) == 8
    PLLCFG = ((Fcclk / Fosc) - 1) | (2 << 5);
#endif
#if (Fcco / Fcclk) == 16
    PLLCFG = ((Fcclk / Fosc) - 1) | (3 << 5);
#endif


    PLLFEED = 0xaa;
    PLLFEED = 0x55;
    while((PLLSTAT & (1 << 10)) == 0);
    PLLCON = 3;
    PLLFEED = 0xaa;
    PLLFEED = 0x55;


        VICIntEnClr = 0xffffffff;
        VICVectAddr = 0;
        VICIntSelect = 0;
        }
