2007 maxxforce 7 dt. No power till 10 minutes of driving.

I got a 2007 International maxxforce 7. The truck has had 0 engine issues for a year. I got no lights on.

Issue
Every morning when I start my truck I have not much power to the point it will only go 5 mph up a hill. It maxes out at 1800 rpm. It will stay like that all day if I dont restart it. What I do is drive down the road for 10 minutes, pull into a parking lot, restart and boom lots of power and will go to 2500 rpm. If I restart after driving for say 5 minutes it wont work.

Some clues

• I changed the oil/fuel/air filter and it happened about 4 days later.

• Its been like this now for 2 months.
  
• It hasnt gotten any worse or better
• It needs the same amount of time till I restart except for a really cold day I had to drive 5 minutes more.
• The oil pressure gauge and ecm reads 88 psi but it has read that for 10 years now I guess
• I changed map/mat sensors as they were gross. I changed the lifter pump too. Just acts of desperation

Any ideas much appreciated
