1990 Ford F150 - Flooding?

[mizshadow420]

Recently my truck has started acting up, it runs fine for the first 5 to 10 mins, then starts to lose its go power, spuddering, and if I keep going, it eventually will die. When its acting up I think i smell a fuel like smell, like its flooding. After it acts up or dies, it has to sit for a few hours before it will run again. Any ideas of the problem or the fix? Automatic Transmission, inline 6, F150 XLT Lariat.

Thanks for any help!

Sounds alot like a clogged cat. Next time, remove the o2 sensor & see if it starts.
