We need some more details. I suppose it could be electrical.
But . . . it also sounds like hydrolock, see here and here. I know very little about it, but as far as I know it often requires an engine replacement. As noted in the wiki article I linked, common damage from hydrolock includes "bent or broken connecting rods, a fractured head, a fractured block, crankcase damage, damaged bearings, or any combination of these."

I drove through about 1or2 ft of water a couple weeks ago. Jeeps supposed to be able to handle 30 inches I believe. I drove slow. The first thing I did was check my air box for water and there was none.
Hydrolock would be your (her) worst case scenario, if the engine took on water. I hope that's not the case.
Oh... My horn sounded like a dying mouse for a week

Well worked three doubles sorry about the delay. She was on a paved road so I will say puddle. After she got to Krogers and came back out to leave it would not stay running intel the therd time???? She said it would rev up to 3000rpm then just stall out. Well thursday took jeep to work did not do it, but I put a can of dry gas in it and filled it up with 93 octain thinking she just got some bad gas. Never had a problem since.
