This could be caused by a bad fuel pump or a defective CPS (crank position sensor). The CPS often fails when it gets hot. Pouring cold water on it can make it start working again. Note that if the CPS has failed the ECU will shut down the fuel pump so this may also present itself as a fuel pump problem.
