Engine Stalls when warm

Engine Stalls when warm
Hey Guys,
I'm a newbie here but found this site to be really informative!
I am having a problem with my 2002 Toyota Tacoma 2.4L automatic. When the truck is first started in the morning, it runs fine until the engine temp reaches a normal level, then the truck stalls. I can tell it stalls because the speedometer drops to 0. The truck then starts right back up automatically and the speedo goes back up to current speed, sometimes the speedo bounces up and down. It also tends to stall at stop lights. The truck always fires back up, but sputters when accelerating for a bit, then smoothes out.
I first cleaned the IAC valve with carb cleaner, same problem.
I then replaced the Idle Air Control valve for a new one, put in a new Throttle Position sensor, changed the fuel filter.
I thought this fixed my problem as the truck started right up and ran good for about 5 minutes. Then as soon as the truck got warm again, it stalled at a stop light. It then sputtered and continued to stall until I could make it home.
No check engine light on
Any ideas??

The issue could be with your IAC or the MAF sensor.
Might need replacing or just a good cleaning. Lots of posts about this stuff.
Do a search for more information.

I've already changed the IAC valve for a new one. The MAF sensor looks brand new when I remove it.
I've searched the forums but cannot find anything that describes my issue exactly. Most are about hard starting at warm temp, the truck has no problems starting, even after the truck stalls

Codes?
Shouldn't the speedometer keep reporting as long as the key is on RUN, regardless of the engine running or not? I'm thinking yes, which makes me think that you might have an intermittent electrical fault. A code scanner can be used to monitor the ECU when the problem occurs.

you would think that the speedo should remain accurate even when the car stalls, but it drops to zero.\
I have heard that it may be the VSS (vehicle speed sensor) that is causing this to occur. Anyone have experience with this sensor?

So after I used the code reader, I got a p0340, camshaft position sensor error. I shut the truck off and looked under the hood for this sensor, could not find it. I went back into the truck and checked the code again and it said no errors, wtf?˟
Where is the camshaft sensor located?
