Fuel issues
Does anybody know where i should start? My 7.3 is running but losing all power. Pumping the fuel pedle will get it started and it will run for a few then lose everything again. Should i just drop the tank and check the sending unit and intake and filters first then work my way up? Thanks for any info?

WELCOME TO FTE!! 
We need a little more to go on before pointing you in any specific direction.
1) Year and mileage, please.
2) Any recent repairs or modifications?
3) Any other symptoms showing up (i.e scanned for codes, rough running, smooth at startup but getting rough as it loses power, etc.)?
4) Ambient temperatures for your startup condition?
5) Have you verified that your oil level is full?
Without having answers to any of the above, I first think along the lines of fuel flow/pressure issues. When our fuel pumps get tired, or just cannot pump the fuel (cold weather gelling, plugged suction line, broken/cracked pickup tube in the tank), it can provide what you've described. Then again, so can low oil level and several other conditions.

Great. Thanks for the follow-up information, and I'm glad you resolved the problem easily enough.
One of my local diesel shops tells me that the single most common problem they find for when a Ford diesel runs rough and shuts down is "low oil level".
