Engine was running fine . Then an alert tone in cab sounded. Volt gauge stopped registering, engine began to idle rough . When driving engine has no power and the exhaust fumes have a terrible smell. What is really strange is when I depress the accelerator the digital odometer flashes. Will not exceed 1300 rpms at idle .

Check battery for condition including load test most places do for free, then scan for codes and check fuel pressure with a gauge auto parts rent it. See link on how to check fuel pump.
