1st and second gear bogging out occasionally

Hello, I own a 92 Dodge Dakota. Im newer to using a stick but dont think this problem is due to my lack of expeirience.
SOmetimes, usually not to long after I start driving, If I have it in 1st or 2nd gear and am traveling a very low steady speed the truck starts bogging out and jerks as if its losing power (never stalls though) soon after it begins it will stop. I dont have my foot on the clutch when this happens and I know im going well over the required rpms (1000) so I dont think its stalling. It will also make a noise that seems to be coming from the rear end when it happens.

Also on a side matter is it ok if its hard to put the stick in first gear, I almost have to force it every time.

If you could help that would be great. Thanks
