1987 Chevrolet S10 Blazer stalling when hot
 

I've had this blazer about a year now. 93k miles and I'm running into a stalling issue. I've changed the ICM, the alternator is new, fuel pump has been replaced, fuel filter was replaced twice, new injectors, serpentine belt was replaced, new idler pulley, rear exhaust was replaced with a new muffler, plugs and wires, cap and rotor, IAC, and the oil has been replaced at 3k mile increments with a new filter. Basically I drive it until it gets to temp and then it will die when I'm at stop lights, idling, and when I'm coasting. It will just die immediately and the battery light, gage light and check engine light will come on until I turn the car off and try and start it again. The car will not start immediately back up and takes about 5 minutes to get it going again. Its been happening a lot and has left me stranded a few times. I'm stumped... What do you all think? I'm also in Florida too and it's hot everyday down here. Thanks guys!

Is it a TBI injection?

I`m thinking coil. they will do this when going bad

Yeah it is

Yeah that was one thing I didn't change yet. Is there a way to test it?

You're talking ignition coil right?

Yes, not sure on the test. May test fine at first but then bad when hot.

Ok sounds like that will be the next replacement on my list. Thanks!

theres also the module connected right next to the coil. i believe those can do the same

So I changed the coil and again it stalled.... I also changed the ignition control module earlier and that wasn't it. I'm about ready to give up on it but I'll change one more thing... Could it be a distributor pickup? A GM mechanic told me that should be next. What do you think?
