Have you verified that the charging system is actually charging?

Use a digital multimeter.  A fully charged battery, without the engine running, should read 12.6 volts.  WITH the engine running, you should see high 13 up to 15 volts.

If not, could be bad alternator,  loose wire, slipping belt, or bad voltage regulator/engine control computer.

Solid advice from Paranoid.

When it said "Check Gauges", did you? What did the gauges say?  I'm guessing very low voltage, likely meaning no alternator output (no battery charging).  After it shuts down, have you checked engine battery voltage?

Since it's a Fleetwood RV, the house charging system will charge the engine battery as well, so try running the generator while you drive and see if the engine stays running.
