Propane troubles

I'm running a stock 89 tbi5.7 350 converted to propane. The motor runs pretty strong other then the tank freezing up on me.

For example: if someone is stuck and I'm having to pull them out or if I'm stuck and I'm hitting rpm's in the 6000 range it'll run those rpm for couple minutes then it'll start bogging out and stalling. That's when I look back and the tank will be ice cold (frozen)
I've tried alum n steel tanks both freeze.
I've talk to a couple people and there saying my motors pulling to much pane causing the tank to freeze.

What can I do to solve this? Anyone else ever had this problem?
Thanks,

run both tanks at the same time,the next thing would be a tank heaters. it's a differential problem in the tank valve acting like an orfice.

I'm sure you know this but have to ask..do you have the tank "clocked" right? If it is sitting at the wrong angle it will do this. Other than that like said above run dual tanks.

It's setting on its side with the hose connecting to the tank valve, let's say if your looking at the tank the valve is a 2 o'clock

I didn't pay attention to how you had it oriented last time you were over. Is it like this?

That hose connects about 4 o'clock, mine at 2.
Would that cause it to freeze

In the pic posted can you see the oblong looking hole cut out of the tank sheet metal? A forklift would have a stud sticking up that the hole in the tank would sit over. This in turn clocks the tank and allows the tanks pickup to work properly.

http://www.patooyee.com/propane/propane_2.htm I think the dual tank set up is going to be your fix, I tried looking for a high flow valve for the tanks but no luck.
