Could this be vaporlock or possibly the efi relay. Fuel pump was recently replaced.

Pumping the accelerator on a fuel injected car is usually a worthless exercise--the technique works on carbureted cars with accelerator pumps. But in your case, it may be helping a bad throttle position sensor make some idle contacts come together. the throttle position sensor has a variable resistor to tell the engine computer where the throttle opening is--and a switch to tell the computer if the throttle is open or closed as at idle. This sensor isn't cheap so I would buy a Haynes manual to help you check it out before replacing it. Some auto parts stores will "read your diagnostic trouble codes or DTC's" for free. Even if your check engine light is not on, some transitory codes can get latched in memory and help you solve the problem.

Try the fuel pump relay. Next try a fuel pump. ( might be getting hott and shutting off.) Finally try a computer, ( i had that same problem and the car was shutting down on the highway ) I put a computer in it and it fixed it for good.
SOURCE: I keep blowing EFI fuses on my Toyota pickup v6 4WD.
i have had this same problem.. check the exhaust pipe near the middle of the truck.. the o2 sensor was hanging down and would blow the efi fuse when the exhaust got hot.. took me months to find it..lol

remove the passenger side of your dash "the glove box" there is a circuit opening relay tucked up behind the speaker it's small box. it reseavs signal from efi and maf then sends power to your pump. good luck...peace and love for all...
