94 ssei loss of power. need help!

let me start by saying i fix cars for a living =) this car has 117,000 miles original engine and trans. when the car gets really hot (driving for long lengths of time) it goes thru a loss of power issue. i can tell its misfiring or something. no engine light at all. my scanner tells me the tps, maf, are both reading when its in this mode. ive changed all injectors, coolant temp, coil packs and module, tune up, oil pressure sending unit, took the egr off and cleaned it, ive unplugged, o2, maf, egr car has no change when these are unplugged and i figured it should have went into a defaul mode on each one. no change. i am lost. this car pisses me off lol. the car has a smaller pulley, no catalayic convertor, gtp injectors, cold air intake.
the traction light is on and sometimes it makes me wonder if the car thinks the wheels are spinning and is trying to shut the power down because of that......im not sure but im gonna try to disable the traction abs system to check. as of now the traction light is on but the abs work fine. once in a while the traction light will be out but comes on after driving...i figure a wheel bearing is causing that. car runs fine when its cold lets say and has tons of power. but when it goes in its"bitch fit" it sucks bad. if i open throttle to 100 percent the car comes out of it and is fast but as soon as i let off to 99 percent throttle its back doing the bitch fit. something tells me its gonna be in the traction system....any help would be appriciated.

Have you ever gotten any codes like a 1361?
