2003 v70 new fuel pump starts runs 10 mins. dies won't start again for a few hours

Check fuel pressure at the injector rail. Could be your fuel pump relay is cutting out. If fuel pressure is good, check for sparks at the plug wires. Read the link below for more info.
Do It Yourself Diagnosis and Repair

check for codes in the PCM if none the I would check fuel pressure and volume. the volume should be about 1 pint in 15 seconds. the fuel pressure should be 35lbs, continually check pressure until the car dies as sometimes a bad fuel pump won`t show up immediately. also change the fuel filter.

Check fuel pressure

change your fuel filter ..your vehicle will run but your fuel pressure is weak ..also after this clean your fuel injectors by pouring injection cleaner in your gas ,,it will correct itself..Also ,,if none of what I stated works ,,Spark plugs and new spark plug wires needed ,,Lastly your fuel pump

did u change your fuel filter? Check fuel pressure with key on engine

Sounds like the fuel pump going bad. You will need to check to make sure you have the correct fuel preasure for at least 10 mins. You can find a fuel preasure tester at any auto parts store. Same thing happened in my 2002 Escalade, replaced the fuel pump for around $650.00. Good luck

fuel pump is a likely cause as it will run fine when cold and once it heats up it loses powers muffles backfires and dies.

Did you try changing fuel pump relay?

sounds like your fuel pump is going out. One thought might be that the fuel filter is causing enough resistance to over heat the pump. I would check the fule pressure to determine a free flow of fuel.
