If you're asking a question you need to give us some specifics. If you just want to vent then I'm sorry you're having trouble.

What coach?

What engine?

Have you checked for codes in the ABS system?

When is last time you flushed all brake fluids out..?? Needs done every 2yrs.. no exceptions.. maybe po, used wrong type.. start there its the ch cheapest.. look in brake reservoir and tell us the color ?.. it should be almost lear.. then start checking a/p.. when was it last maintenance .? Look on a/p brake drum and see if discolored.. they are not related but still need maintenance.. . then look for good grounds... they always need cleaning.. check abs, sensors.. check their connections they get corroded.. blow air though front ads sensor and rotor and blow the rust out.. some here have had rust get in the way of sensor reading the sensor ring.. on rotor.. that is cheapest thing.. use mask.. brake dust is nasty.. do you have special scan tool? Most don't read abs codes.. good luck and let us know what you did and maybe better members then me will help you..

Long shot - last time I had similar fun in a truck, it was a dead alternator. Ran the engine until the battery completely died, and then lights started coming on and the battery wouldn't power the spark plugs and everything coasted to a stop.

ABS might be coincidence ???
Limp mode on .... throttle position sensor / throttle body issue. Or crank position sensor. CPS is bad hard to start will crank 20-30 seconds before fire.
Google there's many more in trucks than RVs
Any other check engine light.
I know some engines through stability control light or code for variable valve timing solenoid issue but I don't think your 8.1 has VVT.
