3.0 Stalling/Power Problem
Now here's the symptoms, and they only happen offroad it runs fine on the street, it will push 35 SSRs to 80+ mph with 4.10 grears. Offroad though it is like it has no power when I am going up hills and stalls out. Its like it just dies or stalls out. The wierdest part is that it only happens offroad either going up steep hills or really bumpy terrain, wallowing through mudholes it did it too. Hard to explain.
The thing that really confuses me is that it only does it whne wheeling and acts fine on the street with as much power as I would expect pushing these tires with stock gears.
Ok so I'm getting codes 24 and 31 thrown at me. I think that's what they are at least. It's hard to tell what that dumb blinking light is doing.
24-
INTAKE AIR TEMPERATURE SENSOR SIGNAL--OPEN OR SHORT IN INTAKE AIR TEMP. SIGNAL
--INTAKE AIR TEMPERATURE CIRCUIT
--INTAKE AIR TEMPERATURE SENSOR
--ECU
31-
MANIFOLD AND/OR AIRFLOW METER SENSOR SIGNAL CIRCUIT
--AIRFLOW METER/CIRCUIT
--MANIFOLD PRESSURE SENSOR/CIRCUIT
--ECU
The AFM checks out fine when I check it with an Ohm meter.
Has anyone else had anything like this happen? I am not so good when it comes to motors.
I should I go about finding this problem.

Since the problem only occurs when the vehicle is at steep angles, your fuel system is the most likely culprit. Suggest checking fuel pressure before and after regulator, fuel filter, and fuel pump for proper operation.

Guessing here... but with the MAF signal, perhaps your intake boot is torn?
I had that happen to me once. Would run fine until bumps, angles. The twisting force would open the intake hose and it would stumble or stall out. On the road is was unoticable.
Check under the hose and between all the bellows thoroughly.
Easy fix though, just replace or go with an upgraded intake pipe.

Makes sense because the motor thinks it's getting less air than it really is.
I don't think it has anything to do with fuel delivery.

Be real careful.... motors don't like water, and it sounds like you may have been lucky so far. 
Just for clarification, with a torn intake the engine actually gets more air than it thinks. Since the engine uses the MAF to sense air intake, and the hole is after the MAF... the computer can't "understand" this additional air and can't compensate.
Thus stalling, bogging down and the extra water. Did I mention that was really bad already?
A super quick and cheap fix is duct tape. Probably hold for months if not longer.

HOLYSHIZNIZZLE!!! Now THAT'S an intake hose tear!!!
91toyota - Where in G'ville you at? I lived there for 3 years to get my microbiology bachelors. Called GatorBack home for those three years too!

I live in a house off of old archer close to 34th. Gatorback as in the motocross track?
I took it to our little local wheeling spot and it works again!

Yeah that is a limerock quarry out there, I might go mountain biking there this weekend actually.
The old limerock quarries in this area make great wheeling too, not just mountain biking. There is actually a really small quarry in town where we go wheeling, but it's a well kept secret, just over a mile from campus.

Good call on the torn tubing. You guys would be surprised how many vehicles I have fixed with these symptons. People bring you a car ready to spend hundreds of dollars to get an engine or transmission repaired, depending on what their friends have told them. The next day I get the pleasure of calling them to pick up their vehicle and there is no charge. I usually tape them up really good and don't charge them but I tell them they can fix it themselves just get the part and I show them how to put it on. I could go ahead and order the part and fix it and they would still be happy and about half ask me to order the part and I make $50 for putting it on. Either way this problem and fix usually makes them my customer for life.

Glad you found the culprit to your problem...you may want to do a REALLY thorough cleaning of the intake now...especially with sucking in a bunch of muddy water...
