Just bought the truck and as I was driving it back all of a sudden it shut of and all the gages went to zero... I pulled over and tried to start it again and it didn't start, so i popped the hood and pushed in all the fuses in and looked over some things... It started right up after that... no more than 10 mins i spent. I drove to auto zone and had them check and it brought up Bank 1 and 2 twice so a total of 4 and it said system to lean. we replaced one of the ignition fuses and didn't really have a problem after that until tonight where i was turning into a parking spot and then it shut off again. Then leaving after 5 mins i got stopped by a light then sat there for 15 secs it shut off once again... so i was wondering if its an electrical problem or something to deal with the fuel filter or pump?

sounds like fuel issue no doubt... i would start with the fuel filter just to see, cheap fix either way you will want to replace it anyways... then if that dont do it look for loose connections on the fuel pump.. most likely thought from my experiences it will be the fuel pump... and if you do replace the fuel pump and it still acts up... check the pressure coming from the pump. i have had two cases where i have replaced the fuel pump and the new one was bad from the git go.
