Former Emergency Management command center. Always maintained but sat for 2 years. 275,000 miles Starts right up and runs fine except that any uphill grade from a stop or slow roll is painfully slow and labored. Once it hits 50 +/- it will scream up hills. Fuel filter and screen are new. Oil is clean. Any ideas?
1999 Int. 4700 T444e no power under 50 mph
