I have replaced the fuel pump and filter and map sensor. Car slow to crank but drive fine for 10 miles with a normal restart during the trip. This morning had to crank 4 or 5 times and mash the accelerator to start, drive fine about 3 miles then shut off from lack of fuel and wouldn't start again. Any suggestions on what to check? Thanks

These engines have an oil level sensor and an oil pressure senser that will cut the fuel pump operation to help save the engine in case of no oil pressure or no oil left inside the engine if the pressure and level is okay the sensor can be bad giving the computer a false positive. Here are the sensor locations so you can check it out. Check out the images (below). Please let us know what happens.
