Test (scan) for any stored fault codes - for free at local auto parts stores.

Specific code(s) = P1450 Unable to Bleed Up Bleed Fuel Tank Vacuum;

Reference the multiple Ford and NHTSA Recalls for the 2013 Ford Escape
#14S17 - S1;
Ford Recall 15V813000;

'Wiring splices to the manifold absolute pressure sensor may be faulty and provide improper signals to the engine's processor. This can cause an engine stall or hesitation. Dealers will replace the current crimped splices with new splices free of charge to resolve the concern.'

Ford Motor Company (Ford) is recalling certain model year 2013 Escape vehicles manufactured January 11, 2012, to April 1, 2013, and 2013-2014 Focus ST vehicles manufactured May 03, 2012, to October 14, 2013. Insufficient compression in the engine wiring harness splices to the Manifold Absolute Pressure (MAP) sensor may provide incorrect signals to the powertrain control module (PCM).
Consequence
The incorrect signals could cause the vehicle to hesitate or the engine to stall, increasing the risk of a crash.
Remedy
Ford will notify owners, and dealers will replace the current crimped splices with new splices, free of charge. The recall began on January 7, 2016. Owners may contact Ford customer service 1-866-436-7332. Ford's number for this recall is 14S17-S1.
Notify
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

There are a few possibilities:

Blocked EVAP canister or purge vent solenoid.
NOTE: the purge valve vapor assembly should be replaced FIRST,

Kinked or collapsed hose between canister and fuel tank
Faulty Fuel Tank Pressure (FTP) sensor
Fuel filler cap stuck closed, preventing vacuum relief
Visual inspection following the fuel tank lines might show a point of damage.

If you're handy with electrical testing, you can take the tubes off and disconnect the solenoid valves and jumper 12 volts to them and see if they open. You can apply compressed air as a basic test.

The canister purge valve is a vital part of the Evaporative Emission Control System (EVAP). The purpose of the EVAP system is to prevent large amounts of fuel vapors from escaping into the atmosphere and from getting into your vehicle. In particular, the canister purge valve is an emissions control component that allows the engine intake vacuum to take the exact amount of fuel vapors from the EVA canister into the engine intake manifold. In newer model vehicles the purge valve is electrically operated solenoid controlled by the engine computer. When your engine is off, the valve is closed. Once your engine is up and running, the computer continuously and moderately opens the purge valve. This action allows fuel vapor to move from the charcoal canister to burn in the engine.
Like many automotive parts, dust and dirt can clog the canister. The purge valve can even crack from harsh conditions in the environment. If the purge valve fails, it can cause problems for the EVAP system which will negatively affect your car's emission output level.

A stuck-open purge valve can cause difficulty starting. A vacuum leak because of a bad vapor canister purge valve, can lead to problems starting your vehicle. This will cause outside air to enter your engine and interfere with the overall internal combustion process. If you have unmetered air mixing with fuel in the cylinder chamber, then it will cause engine problems. The most obvious issue will be an engine that does not start.

Failures of these purge valve solenoids apparently are a common problem ever since a redesign on the Ford Escape in 2009. This failure can cause an over vacuum state in the evaporation system that sucks gasoline into the purge canister ruining it and causing the stalling problems. The purge valve is located in the evap canister by the rear of the car or fuel tank on the 2013 Ford Escape.

As indicated by the service manual, because of where the purge canister is located, you will have to remove the rear subframe, including suspension, driveline, brakes, etc., to replace it.

Unfortunately - there is very expensive labor to replace a $50.00 component!
DORMAN part #911774 - or it's equivalent
WVE part #2M1596 - or it's equivalent
