Engine cutting off problem! 1st Post as a member!

So i just bought a 325i 04 (97k) 3 series about a year ago and i love it. Im glad to be apart of the bmw master race although i have been expiernceing some issues here recently. about 3 months ago my car has been making a high pitched screeching noise upon start. it would slowly go away after driving off. >fast forward a month; screeching noise stops >awesome; so i unfortunatley do not look into it since it did not affect driving. now a couple weeks ago while driving on the hwy going about 80mph i lost power for a split second and the lights on my dash flashed on then off (the battery, oil, check engine and eml light i think) the car then proceeded to drive as normal. this has happened a few times. >fast fwd a week; the engine turned off smoothly while at a stop light and the lights were flashing again. i did not even notice it. turned the car back on and then the accelerator jerked without me stepping on the gas a couple times, i turned the car off then on again and the car drove normal as before. What is going on??? I would appretiate any feedback.

Some things i have jotted down that may be the problem:
sofware update dme, loss spark alternator, fuel pump, fuel filter??? software idle speed, disa unit.

tell me what you guys think!
