lt1 help needed. Please Moved this being I put in wrong section as well as update
car is a 96 camaro.
Ok so the newest of my damn lt1 gremlins. Last week driving home on highway engine dies. Throws a check guage on dash but no service engine light.Pull it into shoulder cranks right up.Drive to work next day flawless, on way home again engine dies. Cranks right back up. So this weekend went ahead and tried trouble shoot. Car throwing/stored no codes.Changed fuel filter,took off and cleand entire throttle body (tps,iac). Checked my connections, threw some techron cleaner in that ho. And let it idle no exageration over an hour. Idles perfect.... Drive to work monday fine.. Coming home hit the light, thing dies again only to crank right up. No hard start, no sputter or anything. When its died my lights/radio/guages on and stay on dont even dim, just engine dies. There is no warning.And its not throwing any codes, just says check guages until restart. ***** driving me crazy, only thing I can possibly think is maybe something to do with elec water pump/relay being its running off my ignition fuse perhaps? All my fuses fine though, and again no other symptoms, running perfect aside from random engine kill. ANY input greatly appreciated..
UPDATE= OK i cleaned IAC, changed TPS. Took it for a drive and opened her up. Idled fine as always.Drove it about 2 miles up rd where I could kick it WOT. First I kind of gave her lil more than half, accelerated fine.Came to stop Floored it, it accelerated flawless(pulled hard) no bucking etc. Then It went into red as though it disregarded shift point. But did not cut out, turned around heading home. Came to stop sign, Died. Cranked right up,with a foot on accelerator.Then proceeded to die again two more times within the 2 mile drive home. Got it home and read that MAP can cause the issue as far as shift points also. So changed that. New map,tps,cleaned IAC. Car cranked, idled fine as always.Then died just sitting there idling threw check guages code.Got it to crank again with foot on gas let it idle about 10 mins. Then it stalled again.So now it seems worse off than it was. Only thing I can possibly thing now is EGR ? Fuel pressure reg? Or maybe my pump is just dying. But none of those explain shift point issue.

Was replaced like 4 months ago right after did opti and plugs. I thought maybe it went out also. But tried the "tap test" and stalls cold or hot. Also couldnt think of how that relate to shift issue.Like use die 100% time at WOT. This time opened up and instead stalling it was just bouncing off rev limiter till i let off
