Engine shuts down when warm

I have a 1999 Tacoma 4 cyl. and it has been shutting down after it warms up to normal operating temp. It won't restart until it has cooled down a bit.
I have replaced just about everything related to the problem (fuel pump, spark plugs and wires, EGR valve, Pressure regulator, and also took apart the throttle body and cleaned that as well.
Any suggestions on what to do next?

Timing? Valves? Vacuum leak?

have you looked under the truck to see if the cat is clogged and glowing red? it will become more restricted when it gets hot and it may be choking the engine.

feel the exhaust pipe when cold and keep feeling it as it warms up to see if you feel the exhaust flow slowing down.

the other thought is your coil is cutting out when it gets hot, to test this, have a "known to be good" spare plug handy and check for spark when it dies

Is the check engine light (CEL) on?

When it stops running you need to determine if it's still sparking when you crank it. If it's still sparking, then you've narrowed it down to a fuel problem. If it's not sparking, then try to figure out if it's the ignition system itself, or a sensor not giving the computer the correct info. I'm thinking the camshaft or crankshaft position sensor since these can exhibit these symptoms, shorting out when hot, but working once they cool off. Although, I'm not sure if these would throw the CEL always if bad.

Coil sounds like a good idea. I had that problem on a vw bug once and it drove me crazy. Thought something was seriously messed up. Turned out to be just the coil. Only happened after it was warmed up.

You might take a look at your EFI relay and wiring. My '91 Land Cruiser would stall out when the engine got warm until I redid the wiring. Not the same vehicle, no, but the symptoms sound similar. Good luck with the hunt!
