several things to look for
1 wiring that runs below timing cover [this is for ign. system and alternator] typically oil soaks the wiring harness and the insulation chafes off [soldier in new wires as required and then heat shrink over the splice]
2 corrosion on the fuse block at drivers kick panel [specifically fuel pump fuses #5&7]
3 insulation cracking off of the main fuel injection harness [a new harness is rather expensive to install but on these cars is usally worth it
4 failing fuel pump[s] and or relay [dont forget the fuel filter when replacing pumps] fuel pree spec is 35 psi and 40 psi with vac hose off of the regulator[no smoking]
5 corrosion at the under hood fuse near battery [reccomend replace fuse holder with a sealed marine type]
note these faults are in no particular order and it would not be suprising to find more than 1 of these listed on a 20 yr old car. unless badly rusted or wrecked a 2 series car is almost always worth repairing. good luck and hope the repairs are inexpensive.
one last possibility is the air mass unit [usally this gives off idle stumbles and acceleration troubles [if unplugged it goes into limp mode with hard starts and poor acceleration but will run fair at 55mph on up just sluggishly if this is an improvement in your situationreplace it and the little thermostat inside the air filter housing.

These cars have so many systems that are intertwined, a definitive answer to your question is purley a guess for the most part. Mine went nuts all of a sudden and I later found out ($417 later) that the Mass Airflow Sensor had failed. This part usually will last the entire life of the vehicle. Take your ride to a competent mechanic and prepare to reach for your wallet in the end.

I assume you mean that it loses power at cruising speed. Initially, this sounds like a fuel problem. It could be a partially clogged filter, water in the gas, partially crimped fuel line, or vapor lock. It could also be an electrical problem caused by a component breaking down because of excessive heat. Only thorough troubleshooting by a competent mechanic with the proper equipment can isolate this problem for you.

Had the same problem -- losing power -- and discovered that the fuel pump was clogged. It happens if you have run out of gas once, and the tank gets water in it. It is an expensive repair, so think twice about it.

replace the fuel filter located on the top of the firewall.
