Hi' my 300 e 1991 does almost the same thing ,it will start up and run good and after a while it will go dead (sometimes) i let it set for about an hour and it will start back up and may run a couple of days before it does it again.it has 12500 on it. Its getting gas ?????? Any suggestions??it happened today after it has sat in garage for about three weeks i drove it to the store (about 2 miles )left it running ,came out and started to go and it started sputtering and cut off,i let it set for two hrs and it cranked right up and i drove it home ...what up??

 

u have to see if u have spark when it wont start u mite get lucky if crank sensor if loosing spark if u find something let me know other wise i have a good parts car.

 

p.s. dont count on it always starting back up thats how my problems began u have to find someone that is realy good with electrical problems if its losing spark and if its losing fuel pressure start with fuel pump relay make sure u have a good fuel filter . let me know i can walk u tru certain things as u can see ive replaced alot
