This issue comes up a few times a year. I'm a bit foggy right now but do some searches and you will find a ton of information. In the mean time here is some fodder. I found on my 08 HR Endeavor that had intermittent issues with the light coming on which would also render my cruise control inop and drove me crazy.
I finally got the courage and used a pair of pliars to remove the front senders. My left one had a gob of grease on the end. The other was clean in the front. Prior to that I thought I found the problem by following the wires up and finding connectors that showed signs of water intrusion. Cleaning those and applying WD 40 did not resolve the issue. My senders on the front look like a T. The rears are only accesible by removing the wheels. Thank goodness I did not have to do that. I have not had an issue since removing and cleaning the fronts.
This said I believe there have been issues with plugged fuel filters. Somehow the engine, transmission and abs all talk together and the systems must thing the traction is bad if the engine is not reaching its full potential.
One cannot argue with success. So do some Searching on the forums. Go to RV.net too and search there.
