4x4Wire's TrailTalk Forums: 97 montero sport hesitation problem

I bought Dats old sport off of cap510 almost a month ago now. Truck has had some maintanance that needs to be addressed and I finally had the chance to get started on it this past friday. First thing I decided to do was new motor mounts and a new transmission mount. After a couple hours of wrenching I was done and took it out for a test drive everything seemed really smooth and no more thumping coming from under the truck. So I took it down to where some small hill climbs are to give it a test and make sure the transmission didn't bounce around under a load. Locked it in 4L started giving the truck some gas to get it over and the truck felt like it wanted to die. So I backed up and tried it again. Same thing. So I pulled it up to flat ground and put it in 2H and shifted into drive. I tried to gun it off the line truck gives me the same reaction. Feels like it wants to die. Once I get passed that initial hesitation I can give it all the gas I want and it just goes real smooth. I can be in park and punch the gas and it doesn't do it. But if I am already moving in first gear and punch the gas it won't do it either. It seems I have to be at a dead stop and lay on the gas then it will hesitate and act like it wants to die. When it feels like it wants to die it is really abrupt to, not like a fuel issue. Tranny problem maybe? any suggestions would be awesome.

Update: I looked at things a little further after posting this. Still couldn't find anything but What I did notice is that the truck actually seems to loose all power for a brief second. Stereo turns off, lights shut off, odometer shuts off, check engine light and A/T light turn on. This all happens for a second. Truck won't die though. Maybe ignition switch issue, engine control module?

Any body who knows me, electrical is NOT my strong point. I won't even install my own stereo. Lordtrunks and Jinstv know this all to well. So be easy on explanations
