Truck dies while driving and no power

[Mward128]

05 6.0 I just did a full egr delete new oil cooler changed to red coolant and I've put about 200 miles on it since then and the truck has been great. Well this morning I started it and it blew a puff of blue smoke and ran a little ruff then cleared up so I started driving and had no power then after about 10 miles it died while coasting. It started back up just fine so I put it in neutral and revved it trying 2 clear it out and it died. It starts no problem just has no power and dies while coasting or revving need help fast.

How clean was your work when installing the oil cooler? Any chance you could have introduced contaminents into the oil system during install?
