You need to determine first if the problem is fuel or spark. I would start it up with the air cleaner off and you have a can of starting fluid spray in your hand. When the engine starts to stumble and die, spray a bit of the starting fluid in the carb. If the engine recovers, then your problem is fuel. If not, it's spark.
You did not say - when this happens and the engine dies, can you start it back up, and the cycle repeats? Or will it not start until some time later on? If it is the latter, how long do you have to wait?

When I try to restart it take a while, and I do it by pressing the accelerator to the floor and it will start slowly. I will perform the test today, but I really think it's a spark issue.

Then go on and troubleshoot from there
That's good advice.. When I purchased the truck the wires were half *** twisted together. I plan to switch the motor out sometime this year, so I haven't tampered with it. I was actually looking for an ignition coil cap to replace the current one.

That sounds like it is flooded. That is the exact procedure for starting a flooded engine, hold the pedal to the floor (to let in max air) and release slowly as the engine purges all the fuel. Are you getting black smoke when you start it this way? Perhaps your float is stuck?

I'm getting a bit of white smoke as it running, you can smell the richness
Just because the engine dies when spraying in starting fluid can not automatically lead you to the decision that it is a spark problem. If carburetor settings are adjusted too rich then that would be a fuel problem.
Have you tried adjusting the carb idle screws as mentioned on the first page of this post? This is relatively easy to do and improper adjustment could surely give the issues that you are talking about. Try turning them both in to lean up the mixture. Also be sure that your choke is functioning properly.
My money is on fuel.
When the engine dies, hustle around to the engine. Climb up in there, and work the throttle. Look down in the carb while doing this and see if the squirters are actually spraying a good stream of fuel. Not dripping, but a good strong stream.
I dont think it would be ignition becaus a coil usually doesnt crap out, then reset itself and work again. They usually die, and stay dead. They arent zombies. And zombies arent even real no matter whay the chubby girls at the mall say.
It would have to be jetted really rich to kill to engine that fast. Pull a plug and see if theyre wet and gassy, like an old man in a hot spring.
Idle air screws wont really affect how the engine runs above idle. Not to the point the engine will die while driving.
Float level could really be an issue. Check that. If its set wrong, youll either use up all the fuel in bowl really quick, or you will get to kuch and fuel will pour down in to the carb.
The fuel in the pics with the filter looks milky, or just not right. Have tou tried running it off of a gravity feed from a bottle? Ive seen a blocked fuel line or filter cause the exact same issue youre having.
It's been raining here, and she doesn't fit in the garage
I will look up the procedure for running the fuel off a gravity line, in addition to checking my fuel lines and filter. I don't have an fuel filter on the frame.
Also.. I looked under the truck and found this hole where gear oil is leaking from.
It could be the coil. I have seen them fail to where, when they get hot, the spark gets too weak and the engine dies. After it cools off, it will run again. We used to spray a can of R12 on them to see if would run again right away, but that was when R12 was 50 cents a can. These days it's better to just replace the coil, they are only about $10-12.
Right after it dies, have you checked to see if you have any spark off the coil? If you have spark, but it is orange, that is still a spark problem. It's supposed to be blue.
I'm getting a bit of white smoke as it running, you can smell the richness
White smoke is water, blue is oil, black is fuel. If it's sooooo rich, the smoke should be black, not white.
