Won't start or will but cuts off or no power

Ok here's the scenario: Everything was fine with the car ('90 240) running strong no problems. Got the oils changed and was told my belts were a bit worn. I figured better get them done sooner that later. After belts were changed start to hear squeaking/whining sound normally when the heat was on. I figured it was the blower motor.
Now (within last 3 days), has occasion when car wont start. All lights come on (check engine, brake failure, etc). The first time it happened I cranked it again and was off. Yesterday, it took a bit of effort to get it on. Seemed to want to cut off when shifting. I upped the idle a little and seemed fine. This morning started fine, seemed as if trying to cut off but kept going. I tried to head to work but as much as I gassed the car it was going it's own speed.

Need some advice on what it could be.

when the car is acting up, turn off and unplug the electrical connection on the air mass sensor. See if car runs better, it won't run great but if it runs better than it did with the air mass sensor plugged up then you need a air mass sensor. (unplugging puts the car in limp home mode)

Found it and disconnected the cable. car would not start at all. I actually thought it may have been loose belts. Went and got them checked out.
Car still does the no power thing. This morning it seemed like it was having trouble shifting. Once the car warmed up a bit it was good to go.
I had checked all fluids and they were fine. Does MAP act up until warm?

K had belts checked. they are good. cutoff problem has not happened again. on way to have belts check, while there or back. Did disconnect map and the cut off problem duplicated itself so I know that. Replaced air filter. cleaned everything out. Had checked fluids and was fine. Oil was changed less than 3000 miles ago. Today heading to work seemed as if car was having trouble shifting. I would gas it and it would rev but seemed to be taking time to accelerate and shift. Once car got warm though no problems ran smooth. Dont' know if that's the MAP or not.
