Hard start, also losing power and dying on take off.

Alright here goes.
I have a 99 7.3 intercooled. 4x4.
It originally only had a hard start in the morning if the block heater wasn't plugged in... If the block heater wasn't plugged in I would crank it and it would warm and sometimes start if the batteries (brand new) didnt get to low for the starter... It would smoke white, probably from raw fuel then eventually would start. BUTTTT now it has another issue that just recently started happening. It'll start and idle ok, then when i take off and drive down the road at around 2000 rpm it would lose power and eventually die off while driving, and would start up after but drive rough for a bit, then be fine after that... now I can barely leave it in park and if i throttle to 2000rpm the engine does the same thing.
Sometimes it throws the engine light sometimes it doesn't.
I have been reading all around trying to figure out what this is, but have not.

Input is greatly appreciated.

p.s.
The only mods done to this truck is ,a 5" from turbo back, new tranny, new t-case, suspension lift ect... No chip no programmer...
I can't say it never has had one though.

Thank you
Zach

Have you had the codes read?

Assuming if the bh is plugged in, it starts and runs fine.

Have you checked your glow plugs or the GP relay? How long after you start it do you take off? Do you let it warm up, how long? The reason I ask that is that these engines have a EBPV (Exhaust back pressure valve) When it's cold, it closed to help the engine warm up faster. If you're taking off right after it closes (Which I've done) the engine feels sluggish.

Hope this helps some. I'm sure others will jump to help - We have some good knowledgable folks on here.

Thanks for the response. If the bh is plugged in for a few hours or over night it USED to start up and run fine. However now, even if I let the engine idle and warm up it still displays these characteristics. Ive sat and let the turbo spool up and warm the engine and still had these issues.

I have not had the codes read yet because I have no access to a scanner at this point in time. Can't afford to pay for a scanner hook up too broke.
And, I would have checked the relay today but it poured rain all day and still is. I appreciate the post

I have not, I'm hoping the same person with the scanner will check fuel pressure too. And, I am unfamiliar with a cps.

CPS = Cam Position Sensor. 7.3L engines have a recall on them to replace them.

Check here to see what recalls your truck may have:
Recall Information - Ford - You just need to type in your VIN number.

If it is the cps, would that cause the surging and stalling?
The only thing that came up for my recall is
"Recall: 09S09
Description: SPEED CONTROL SYSTEM MODIFICATION"

Have you tried changing the fuel filter.

The symptoms you describe from your latest adventure, suggest it is running out of fuel.

Start with the cheap part first ( filter ) and work your way out.

Also, if this problem only happens when the tank level is low, then you might have a problem with the pickup. Easy test for this is to fill up, and see if the problem goes away.

The cps can and will make them just quit.... anytime! every second, or once a year..
