[Armour]

hey guys, i got a 2005 f-350 psd, afe cold air 4" mbrp turbo back exhaust 6" lift with 35's, i just recently had my egr delete done ( 5 days ago). truck has ran great then tonight driving out to work everything is all good till i hit hills. i i start to accelerate at the bottom of the hill and my truck seem to be reving fine but i am loosing all speed going from 120km/h down to 60 km/h and i can not get any of my seed back till the flats then the truck runs fine again. Then go to drive the truck home from work this morning started it up seemed to idle fine then went to get on the highway and couldnt go over 50km/h when i let of the pedal the and went in neutral the truck sounded like it was chugging really slow about to die, i kept driving into the next town going 50 km/h then i pulled over revved the truck up for a bit then accelerated away fine till 80 km/h and same problem then the truck finally died. i cranked and cranked till it finally started then went about a km more and died. cranked but would not start then boosted it and crawled to town and parked it in a shop for the day ANY IDEAS??????? bad lift pump??? bad filter? gelled fuel. i am working and am away from the truck just need some ideaas of what to look for when i get back to the truck tommorow night. also have been having problems with my battery dieing ( i know i could use new batt's) my truck will stay at low voltage after a boost unless i keep my truck hooked up to another truck for 5 minutes to get power to my truck, my radio wont even turn on gauges wont work and my lights go dim could i also have an alternator porblem and could these problems all be related? when i started my truck to drive it and it was crapping out it was -33 degrees celcius which i beleive is - 27 degrees farenhite if this helps. thanks alot any help is greatly appreciated.

Just by reading the temperature, I am going to guess it could be gelled up.
When were your fuel filters changed last?
Are you running any additive?

I am by no means a mechanic, that is just the first thing that popped into my head.

yes i was using power service fuel additive with cetane boost and it has an anti geller. i just b ran a tank of fuel through it blew the egr, did the egr delete, then drove it maybe 400 km and now am having this problem. i have no clue when the filters were done so im gonna do them anyway.

it was also only making 20 psi boost, when i usaully hit 27 psi, when i did the egr delete the mechanic said my cold air had been letting in quite a bit of dust. could i have clogged vanes?
