Help! '90 300E stalled and won't start. OVP?

Hello,

I'll try and be brief.

Driving to auto parts store to get oil for fall oil change. Doing about 40 and then braking to stop for traffic. Car dies before I stop. Warning lights come on as the car died.

This has happened three or four times this week but I could always restart it. Not now. It cranks with gleeful abandon but it doesn't start.

OVP, MAS or Fuel Pump Relay? I've heard that the MAS replaced the FPR on the 1990 cars.

Before ordering parts, any advice so I am not flying blind?

Thanks.

PS: On a brighter note, I saw a new E500 at MB of Chicago a few days ago. What a nice car!
