My GTP runs 15 mins and looses fuel pressure.. Fuel pump is new

most commonly found problem relates to an electronic component heating up and shutting down. Have you checked to confirm there is fuel pressure when the vehicle shuts off. Is the check engine light on. Have you checked codes ? I suggest hooking up a fuel pressure gauge and letting vehicle run till it shuts off while monitoring the fuel pressure. If you loose fuel pressure, next step is to confirm there power going to the pump, if there is power going to the pump with no fuel pressure replace pump. Another suggestion would be to check for spark when vehicle stops running to eliminate an ignition problem. good luck

Fuel pump going out. Once it gets warm after 15 mins the o rings loosen up and cause it to loose prime and shut off. After cooling for 15 mins they have shrunk enough to build pressure again.

Sounds like a fuel pump failure

Check for Codes
Check Fuel Pressure,listen for pump at the tank
Check for Spark or Injector Pulse
Check Battery Voltage & Alternator Output

Your loosing one of them or other things

sounds like you have a fuel pump problem, fuel pumps will usually get hot and then shut off allowing it to sit 30 mins lets the pump cool down allowing it to start pumping, the way you can test it is get a can of starting fluid the next time it quits raise your hood and spray some fluid down into the throttle body and if it starts and then dies it is most likely your fuel pump, hope this helps.

check your fuel filters, fuel line, and fuel pump

bad fuel pump.- just replace it and your good to go!

t.p.s. censor

try losing your fuel cap, it sounds like its vapor locking!!!!!!!

yep i seen it in happen .i was at a gas station a guy drove car to the gas station on empty.he fill his tank up .could not get it to crank .some cars you have to restart fuel pump when run out of gas. like chrysler.you use a scanner. but chervrolet you run low over heat damage the pump.it has to stay submerge gas to keep it cool. check fuel pump pressure.it should be 41 - 47 psi.

is this a supper cahrged grand prix if so check fuel pump resistor located behind right front head light or on fire wall its made of white ceramic has to wires going to it jump the two wire on the connection going to it if it runs longer then 15 min then replace resiustor.
