Have a 98 Monaco Signature with a M11 Cummins. temperature outside is 90 F.
Today when I started the coach it ran about 30 seconds then quit. I could start it if I waited a few seconds only to have the engine quit. I tried this several times only to have the engine stop. I left the coach for a couple of hours and was able to drive around the block only to have it stop again. It is if I shut the key off but don't the dash shuts off then a few seconds the dash lights up and then it will start only to stop a few seconds later.
I am on a trip and the coach has run great up until this point.
It started after my coach got stuck in the grass. The coach's right wheels sank into grass and I had to be towed out. I don't think this had anything to do with my problem as no mud was stuck to the undercarriage .
Has anyone had this happen or have any ideas. thank you

Sounds like an electrical problem. First I would check the grounds around the frame to make sure one of them didn't get pulled loose when you were towed.

If your dash lights go dead each times this happens, You have a power solonoid that is bad. The solonoid opens the fuel shut off valve and allows the fuel to flow to the engine. Remember diesels have no ignition and will run forever until you turn off the fuel. If your switch goes bad or the fuel solonoid goes bad you will lose fuel flow.

JLF is right also. If you are losing battery power the same thing would happen.

Is this a relay or a solenoid ? the power solenoid sounds logical, do you have an idea where it is located? thanks for everyones ideas.

.On Gulfstreams it is located in the elec. compartment by the left front wheel. In some other manuf. it is in the engine compartment. It is a solonoid.

it usually has two big wires. one coming in to each side and 1 or 2 small wires at the front.

I will try to locate the solenoid later. I know I have a couple of solenoids in the left front. Hopefully I will be able to hear it trying to work or feel it. thanks for the info. I am in Manitoba vacationing and I was told that the truck stops are eight days behind and I cannot wait that long. Once I locate the solenoid I should be able to jump it and keep the coach running but I will have to remove it to stop it running.

fuel filter?

That is exactly what I did when we had this happen on the way to RV shows. Take the large lead loose from one side of the solonoid and piggyback it to the other side,

the ignition solenoid is in the front run bay (front driver side) ....there are two solenoids....one for "accessory" energized when key in accessory or run position .....and the other energizes a terminal strip in that bay for every thing with power when you turn the key to run position (small power wires on solenoid run to ignition switch and a local ground)
The solenoid is a continuous duty and sometimes need to be replaced.
MY best guess is this.....the power supply from the ignition switch to the solenoid has a bad spade connector at the switch itself..........I had to squeeze the spade to tighten the contact and problem fixed.
open the compartment ....put a volt meter on the small terminls at the solonoid and start the engine .....should read battery volts.....when it stalls if no volts you have a loose wire at the ignition switch (key)

It's a new day and now I cannot get the problem to reoccur. I have bought a new solenoid to replace once I know which one is bad. I will also check the spade terminals at the ignition switch
Thank you for all the good ideas. Steve

Steve
In order to point you straight the problem has to be surfaced ....when it does....chech the voltage at the solonoid (small terminals) to confirm it
Something intermittent as you have points to loose spade terminals on the ignition switch itself.......carefully remove the screws and pull out the dash enough to access the rear of the switch and wiggle the wires to find the loose one (I have complete wireing drawing for my coach ...99 Exec and yours will be similar i suspect....if you need wire color codeing
