My MMH just went loopy. Engine cuts out when its under heavy load with a "STOP SAFELY NOW" message. When the engine cuts out the engine fan stays on.... I get an MIL on the "STOP SAFELY NOW" message, but I didn't have my SG with me to pull code. Whatever code was there has been cleared.

As soon as I turn the car off, I can turn it back on... Everything is fine if I'm easy on it, but if I put heavy load on it (2500 rpm-ish) it cuts out again.

Thoughts?

Found a good thread on this at Edmunds.

Sounds like the water pump (factory pump often blows under 50k). If it is the water pump, repair could run between 650-900 dollars, depending on the mood of your dealer.

Just had the MECS pump replaced at 70500 after having that trouble this past week. Dealer said there was a TSB about it and the new pump is much smaller size and different from the original. Don't know the cost as mine was done under Mercury ESP.

 

It is definitely the MEC (electric motor coolant system) pump. Mine did the same thing on a thousand mile road trip to San Diego several times before dying on the way home in the middle of the Central Valley of California. It cost $600 to replace at the dealer. If you are at home with toolkit and jack stands, you can buy the pump itself for around $300 and do a relatively simple change out in about an hour.

Ford has an advisory notice about this problem, and there is a class-action lawsuit pending.
