Your alternator is weak or the battery cables are bad (+ and -). First measure voltage at the bat with engine running and as many accessories on as you can. If voltage is below 13, check cables. If cables are good, have alt tested.

Just about everything on your vehicle needs voltage to run. Without at least 10 volts or more available to electronic systems, the vehicle may not even run.
