Thrash, if you tune your truck in your yard at let's say 4pm, then run it at Leisure at 8pm, it will need to be re-tuned (most of the time). The temp ouside would have dropped at least 10 degrees causing you to have to richen the HSN.
Basically if your truck is running real good and fast, yet it cuts off alot, it's too lean and overheating. Plus when I was there last night I was saying to myself that your truck looked to lean. I think if you turn your HSN back (richen it) about 1/2 turn would be a good starting point (yes a full 1/2 turn, don't be scared to turn the needles, you can always turn them back to where they were). If it's too rich after the 1/2 turn back then slowly start leaning it again.
There is two main reasons for a truck to cut off during use. it's either too lean and overheating or not getting enough fuel in the motor to stay running, or, it's too rich and dumping too much fuel in the motor and putting the fire out.
Looking at your truck last night, it was fast and I'm suspecting it was too lean.
