Well, everything was running fine with this Cummins ISX15 525hp when we stopped on a grade (3% maybe) for one way traffic. Suddenly the eng idled badly and it blew a bunch of white smoke and died. No temp issues etc. I tried to start the generator and it blew white smoke ran for a few seconds and died. Now neither will start.
Only common thing I think is fuel. It's diesel ran a full tank down to 3/4ish no issues. Roadmaster chasis. No sure what's going on. Stick on a hill in the middle of nowhere and completely screwed. Help

Did someone put gas in your tank?

No... Noone touched for 200 miles as was. Unless they did it in dark... Unlikely just drove another 100 miles since overnight

If your fuel tank is low and you’re on an uneven surface it’s possible you have sucked air from fuel tank or bad fuel (water or other contaminants) from the bottom of the tank. It’s possible your gauge is off a bit. On my diesel motor home my gauge will show a quarter tank one minute and the “E” shortly after.
See if you can get some fuel delivered and try bleeding the system. If that don’t work you’ll have to have it towed in.

A tow may be required but drain any water from the fuel filter if so equipped. Replace the fuel filters. You may have debri in the tank that got stirred up with the sloshing with the low fuel level and the hill. If you don't have fuel filters buy at least 2 sets and hopefully you can get to some help.
Save the old filters to cut open and inspect which may help with determining any required tank cleaning.

My gen intake is set to suck air at about 3/8 level which is common to prevent running dry for the engine. Low level light is about 1/4 tank and E on the gauge is about 100 gal for a 130 gal tank. It's a shallow 7.5' cross tank and all of this is designed to help prevent sucking air which causes a diesel to immediately stop.

White smoke is typically the result of one of a number of bad things, however there is only a couple of things that could afflict 2 different engines.
That is water in the fuel, enough to overwhelm the fuel water separator on the rig’s engine.
It’s hard to believe that’s the issue though considering how high the pickup for the genset is.

Smoke is black or gray
Steam is white
"White Smoke" suggests one of two thigns
Water got into the fuel bad enough to become significant
Blown head gasket.
The fact it happened on both the MAIN engine and the Generator in short order suggests water in the fuel tank. lots of it. Now that is fairly easy to fix.
On the other hand.... it could be EXPENSIVE if I'm wrong.
Home was where I park it. but alas the.

White smoke suggests water. Drain fuel from your primary fuel filter and collect the contents in a clear container…the primary filter is likely on the left side of the engine compartment and has a drain on the bottom. The secondary filter is on the passenger side of the engine… remove the filter and collect the contents…any water? Turn the key on for 30 seconds 2 times after draining the primary and 5 times for the secondary… this will replace the lost fuel in the filter.
The generator doing the same thing doesn’t make sense if it’s water as the pickup is not on the bottom of the tank. Your fuel pickups are on the right side of the tank…was the rig leaning to the right more than normal when this happened?
