Default Starting Problem, New fuel pump and mod

I have a 1993 ls 400, would start fine , drive 7, 8 miles stop, try to start , sounds like trying to start a newer lexus without the computer chip . Let it sit for 30 minutes starts up fine, carried to dealer and they replaced the fuel pump and module, $ 1100 or so , drove home still does same thing . Wait about 30 40 minutes and it starts. What do you all think, will take back Monday

Read the thread below this one... Replace the fuel resistor or ECU capacitor is blown. Check those out before you spend that kind of money at the dealer. I would return it and tell them to fix it for free since they didn't the first time.
