Help

I have a 1978 CJ 5 it has the Iron Duke 4 cylinder in it. I was driving down the road the other day in 4th gear going up hill and felt a sudden slip through the gas peddle. The engine then would only rev when i pushed the gas. I down shifted to 3rd gear and it grabbed and as soon as I pushed the gas again I felt the same slip again. I put it in neutral and the engine shut completely off. I have yet to get it started again. The engine turns over like it wants to start but it will not. If I try to start the engine and put it in gear it grabs like it wants to go but the engine will not start. I'm at a total loss and I do not know what to do. Any suggestions would be great , thanks!

That's what it sounds like to me. It's a simple thing to try. Try putting a few gallons in the tank and you might have to squirt a little gas in the carburetor and then crank. Or maybe some starting fluid. Just to get it primed. I think they say an engine has to have , fire, fuel, and air, and I don't know if there is 4th one, to start.

It's spark, fuel, and compression.

The 4th is "TIME"
spark,fuel & air, and they have to get there at the right time.
