I was driving to work this morning and I just got off the freeway arriving at a stop light and the engine just cut out on me, it would crank over the the RPMs would dip and it would cut out. Had to keep my foot on the gas when cranking to keep it from dying, also had to keep my foot on the brake and gas to keep it from dying at the light. Couple minutes later it was running fine, this had happened once before when I was I pushing it. Rarely drive it fast, this time I was running late to work so I had to gas it a little more. Already had 80% of the vacuum lines changed, did the the coil packs, spark plugs, spark plug wires, and cleaned the MAF sensor. Any suggestions of what this might be?

Sounds like a fuel problem
I would start simple. fuel filter first

It is often overlooked but put in a new EFI relay under the hood in the main box. I recently had a similar issue and swapped it out and it solved it. Not saying it is the same with your rig but relays do go bad and we often overlook them and spend $$$$ chasing problems associated with a simple relay.....
The relay should be testable.
But, even if it tests good, doesn't mean it doesn't fail intermittently. Thus, I guess you have a good point/suggestion.

I have a similar problem, my 1998 4runner has a p0335 code so it stalls intermittently, I changed the crankshaft sensor once and it didn't fix it.

Definitely consider the relay route and after 183K - DEFINITELY the fuel filter. (I change my fuel filter out every 2 years).
The relays can be tested but for me (I am sometimes lazy) I would just rather pop a new relay in. Relays generally last a very long time but they do develop problems. I have actually replaced all relays in one vehicle after I bought it used. Ironically, it cut out while waiting to turn and in that case (as well as with my T4R) was the EFI relay.
One other note; if I find a rig at places like PullAPart, I pull the relays and keep them in a bag. They are way cheap and nice to have some extras on hand.
Probably go to this pick-a-part I know in the IE area, probably stop over this weekend a pull some relays out to have as spares as long as they're good lol

I always pull things "just in case" when I find a good rig at a pic-yard. Things like:
Airboxes
ECU
Throttle Bodies
Starters
Wheels/Rims
Main Circuit block (Drivers side by left foot)
Door lock actuators
Center console cup holders
Carbon/EVAP Canisters
Roof racks
Rear Window Glass
Relays
Door panels
Etc., Etc., Etc.,
Maybe I should open my own little "T4R Junkyard! LOL

Stalling at idle is classic issue with a gummed up Idle Air Controller (IAC). Suggest you clean it. While you have it apart, clean the throttle body, too. If you try to clean the throttle body in-place, care should be taken to avoid gunk flowing down into the IAC (through the small hole in front of the throttle plate) which can make the problem worse.

I was planning on just taking off the throttle body and clean it while its off the manifold to make it easier, I had a rough idle on my 92 chevy pickup and replaced the IAC and it fixed the problem of rough idling. I'll defiantly look into the IAC.

Sounds like the IAC issue I had a few years ago.
