Car cuts off while driving

This rather sounds like an electrical problem that is taking power to the DME or coil away. One check would be to see if the voltage at the coil, DME power inputs and DME start input are within a tenth of a volt of system voltage as measured at the power block in the engine bay. If one has more voltage drop than that there may be a poor connection in that circuit. -
yeah, i hear you... i don't have another motor however, so i'm trying to figure out why the same thing is happening to my m20. its strange as hell, every mechanic i've talked to can't come up with a diagnosis.Leave a comment:

wow, thats never happened to me when i drove it... which was a decent amount, about 35 miles every time i took it to school about 20 times.
my 85 325e has been doing the same thing, but only when its really hot out. it did it a couple times last summer on 100 degrees + days. it did it today again. its a tricky problem to diagnose, and i'm looking into it to find out myself right now.
i thought you had a different motor for it anyway?
i'll be following this thread as i am experiencing the same bs.
car drives great any other time, but when its really hot out it just cuts off and stalls out. then i'll stop and restart fine, but as soon as i start giving it throttle it falls on its face again. did it earlier today, let it sit for 15 mins, and it started right up and made it back home about 2 miles. also i drove it all night w/o any problems...
anyone know what this could be because i'm stumped???Leave a comment:

Car cuts off while driving
Well here's the skinny Got an 88 325 courtesy of ubernasty drove the car all the way home (60 miles) with no problems. I changed the timing belt, idler pully, water pump and gasket, oil and filter, all the belts and hoses, brake fluid, coolant, fuel filter and a new tank of gas. But when I drive it it randomly cuts off sometimes. It doesn't stutter or jerk it just smooth cuts off and I coast to a stop. As soon as Im stopped it starts right back up and drives like nothing happened. Does anyone know what could be causing this?Tags: None
