92 SL2 DOHC Lots of problems

I have alot of problems with my 92 saturn. its got over 350K. One of the problems is I ll be drving along doin around 80km/h and the car just about turns off, everything pretty much shuts off for a split second then starts all back up on its own, any one know what this might be? It also chugs and idles really low and occastionally stalls, Ive tried changing the plugs and the fuel filter, but still no change, any idea's? And my final problem is it keeps blowing fuses for the power locks. I changed them about 4 times in one day, the fuse will work for a short while then after a lil while it just blows, any thoughts?

if anyone could help me wit any of these problems it would be greatly appreciated?

to be honest.. sounds like your car is ready for "the long sleep".

But if you really want to keep your car. I would suggest having the wiring checked out. sounds like you have some grounding issues.
As far as your power loss. Have you cleaned the Throttle-Body?
You meantioned, plugs, what about plug wires?

I'm having the same set of problems with my `92 SL2 and I only have 75,000 miles on mine! :(
