V10 hesitation often dirty throttle body, weak coil, or fuel pressure. Clean throttle body and MAF first. Check fuel pressure under load.
For your E450 V10 with 8-16 miles monthly on dusty dirt roads, change the air filter every 12,000-15,000 miles instead of the manual's 30k recommendation. Check and clean it every 3,000 miles.
