PIC16F18877: Using I2C to read sensor (LSM9DS0) value
Your code structure is off and you are ignoring things like ACK.

Here is what the datasheet states the correct structure is. 


The user generates a Start condition by setting
the SEN bit of the SSPxCON2 register.
SSPxIF is set by hardware on completion of the
Start.
SSPxIF is cleared by software.
User writes SSPxBUF with the slave address to
transmit and the R/W bit set.
Address is shifted out the SDA pin until all eight
bits are transmitted. Transmission begins as
soon as SSPxBUF is written to.
The MSSP module shifts in the ACK bit from the
slave device and writes its value into the
ACKSTAT bit of the SSPxCON2 register.
The MSSP module generates an interrupt at the
end of the ninth clock cycle by setting the
SSPxIF bit.
User sets the RCEN bit of the SSPxCON2
register and the master clocks in a byte from the
slave.
After the eighth falling edge of SCL, SSPxIF and
BF are set.
Master clears SSPxIF and reads the received
byte from SSPxBUF, clears BF.
Master sets ACK value sent to slave in ACKDT
bit of the SSPxCON2 register and initiates the
ACK by setting the ACKEN bit.
Master’s ACK is clocked out to the slave and
SSPxIF is set.
User clears SSPxIF.
Steps 8-13 are repeated for each received byte
from the slave.
Master sends a not ACK or Stop to end
communication.
