Intermitent issue

[billybobby]

My truck is having issue's. It started missing bad at high RPM only when the tires are lighting fires. If I hammer it on a 15 mph roll it ran fine. I came out to start it the other day and it would start run for a few seconds then die the second I gave her gas. I came back out an hour later and tried it again it ran fine? I drove over to my buddies and shut it down it did the same thing this time it fired up and ran normal after about 15 tries. It is not setting any codes I couldn't get it to miss unless the tires were spinning. Help please Last time I had a issue I took it to three different shops. They all jacked parts at it and charged me a ton of money before I finally asked some questions on here and fixed it myself.
